Options (RPO Codes) specific to '93-'02 Camaros

What in the world do these RPO codes mean in English, and what does such and such mean I have?

RPO codes are what tell you what options your Camaro came with. They are listed on a sticker in your glove compartment for the early years and on the driver's side door for the later years.

History of RPO codes

Via Camaro: Fifty Years of Chevy Performance by Mike Mueller: In 1963, Chevrolet Motor Division officials revised their options coding system, dropping the three-digit nomenclature used previously in favor of an alphanumeric Regular Production Option (RPO) list that cleanly broke down the seemingly countless codes into related groups. For example, all Chevy engines were tagged with an “L” prefix, all transmissions with an “M.” The really good stuff was found in the “Z” category, labeled “Chevrolet Special Items.” Z11, Z16, Z28—you get the picture.

Decoding RPO codes

RPO codes, in my opinion, are VERY hard to get specific with and remain factual. Generalizations that span years and years of production are not always accurate. They are a big pain in the butt and require incredible research from year to year. For example, one RPO code may be required with a certain package in one year but not required as part of the package in another year. Also, many RPO codes FORCE another set of options onto a car. It's very tricky to get these details perfect, so I may skip a few specifics at first. It's not purely coincidental that many RPO code lists skip many of the codes that appear on 4th gens. They can get really, really complicated.

If you think I've listed a mistake, please email me.

Manifest codes:

If you're lucky enough, you may have the manifest (also called the build sheet) for your car, which may feel a little bit like a birth certificate for your car. Sometimes original owners of Camaros would find these sheets of paper under the carpet, hidden in the trunk, or other places inside their vehicles. 

The manifest is like a recipe for how to build each vehicle. They are unique in that they have the original order number and VIN assigned on them. They were supposed to be removed from the car at the end of assembly and thrown away, but they often were not. There are codes for specific springs, shocks, radios, etc. They are so obfuscated that they are essentially meaningless to most people (including me).

Decoding manifests is beyond the scope of my knowledge and always will be. The entire thing is just confusing nonsense to me.

These sheets cannot be reproduced because GM would purge them from the system once the car left the assembly plant.

RPO codes:

I will only be decoding RPO codes, like those shown on the example sticker. I will not be decoding manifest codes, and never will be.

For early 4th gens, you'll find this sticker on the inside of the passenger-side glovebox. On later 4th gens, you'll find this sticker on the driver-side door's edge.

01U

01U was used to identify a special exterior paint color at GM. Although many claim 01U means two-tone paint, it literally just means a special exterior paint color. The RPO code AAT denoted two-tone paint. For example pictures, please refer to AAT below.

Production #s:

1993: 653 (all were Indy pace car replica coupes with AAT)

1994: 0

1995: 0

1996: 50 (all were B4C coupes with AAT)

1997: 0

1998: 15 (all were B4C coupes with AAT)

1999: 0

2000: 24 (all were B4C coupes, 10 with AAT, 14 without AAT--email me if you know anything)

2001: 0

2002: 13 (all were B4C coupes with AAT)

1AA

Retail Amenity Delete. This code appears on a variety of Camaros, and I haven't looked at enough of them to figure out the pattern yet. 

It appears on all 49 of the '97 Brickyard 400 festival cars (the ones without Hugger Orange stripes). Supposedly all of the August 2, 1997 festival cars had 1AA and R7G.

1AY

Stock Orders Processing Option. This means the car was ordered for dealer stock and not for a specific customer. It may not apply to all years. I believe the equivalent for 2002 is SLM.

1AZ

Sold Orders Processing Option.

This code means the car was ordered by a specific customer and not for dealership stock. It may not apply to all years. I believe the equivalent for 2002 is R9Z or SLL. It appears on a variety of Camaros, and I haven't figured out the pattern yet.

I saw it on a '97 black Z28 coupe with 1AA (specifically, blk97z28's car). 

17P

Wheel color - Silver.

This was seen on a white '94 Z28 that was a Puerto Rican export car as well as a white '94 Z28 that was a typical American Z28. This code likely exists specifically for 1994 due to 40P (white wheels) existing as an option for exclusively Arctic White Camaros in 1994.

1SA

This is one of the codes that you cannot necessarily generalize to all years 1993 to 2002. As such, I will specify which year I am referring to.

In 1999, for V6 Camaro Coupes (1FP87) and V6 Camaro Convertibles (1FP67)... 1SA was "Base Preferred Equipment Group", in other words, a Camaro with "Standard Equipment."

1SB

This is one of the codes that you cannot necessarily generalize to all years 1993 to 2002. As such, I will specify which year I am referring to.

In 1999, for V6 Camaro Coupes (1FP87)... 1SB was "Preferred Equipment Group 1" which included "Base Preferred Equipment Group", Electronic Speed Control with Resume, Remote Hatch Release, Power Door Lock System, and Fog Lamps.

In 1999, for V6 Camaro Convertibles (1FP67)... 1SB was "Preferred Equipment Group 1" which included "Base Preferred Equipment Group", Electronic Speed Control with Resume, Remote Trunk Release, Power Door Lock System, Fog Lamps, Power Windows with Driver's Side Express Down Feature, Sport Dual Remote Electric Mirrors, Leather Wrapped Steering Wheel - Transmission Shifter - Parking Brake Release Handle, Remote Keyless Entry with Illuminated Interior Feature, Theft Deterrent Alarm System, Body Side Color-Keyed Moldings, and Carpeted Rear Floor Mats.

1SC

This is one of the codes that you cannot necessarily generalize to all years 1993 to 2002. As such, I will specify which year I am referring to.

In 1999, for V6 Camaro Coupes (1FP87)... 1SC was "Preferred Equipment Group 2" which included "Base Preferred Equipment Group", Electronic Speed Control with Resume, Remote Hatch Release, Power Door Lock System, Fog Lamps, Power Windows with Driver's Side Express Down Feature, Sport Dual Remote Electric Mirrors, Leather Wrapped Steering Wheel - Transmission Shifter - Parking Brake Release Handle, Remote Keyless Entry with Illuminated Interior Feature, and Theft Deterrent Alarm System.

In 1999, for V6 Camaro Convertibles (1FP67)... 1SC did not exist. 1SB was the equivalent of this for Convertibles.

In 1999, for V8 Camaro Convertibles (1FP67)... 1SC was the ONLY way you could option a Z28 Convertible in 1999. It was "Base Preferred Equipment Group 1" which included "Base Preferred Equipment Group", Electronic Speed Control with Resume, Remote Trunk Release, Power Door Lock System, Fog Lamps, Power Windows with Driver's Side Express Down Feature, Sport Dual Remote Electric Mirrors, Leather Wrapped Steering Wheel - Transmission Shifter - Parking Brake Release Handle, Remote Keyless Entry with Illuminated Interior Feature, Theft Deterrent Alarm System, 6-Way Power Driver Seat, Body Side Color-Keyed Moldings, and Carpeted Rear Floor Mats.

1SD

This is one of the codes that you cannot necessarily generalize to all years 1993 to 2002. As such, I will specify which year I am referring to.

In 1999, for V8 Camaro Coupes (1FP87)... 1SD was "Base Preferred Equipment Group", in other words, a Camaro Z28 with "Standard Equipment."

1SE

This is one of the codes that you cannot necessarily generalize to all years 1993 to 2002. As such, I will specify which year I am referring to.

In 1999, for V8 Camaro Coupes (1FP87)... 1SE was "Preferred Equipment Group 1" which included "Base Preferred Equipment Group", Electronic Speed Control with Resume, Remote Hatch Release, Power Door Lock System, Fog Lamps, Power Windows with Driver's Side Express Down Feature, Sport Dual Remote Electric Mirrors, Leather Wrapped Steering Wheel - Transmission Shifter - Parking Brake Release Handle, Remote Keyless Entry with Illuminated Interior Feature, Theft Deterrent Alarm System, 6-Way Power Driver Seat, Body Side Color-Keyed Moldings, and Carpeted Rear Floor Mats.

I'll do some sort of formatting and more info with this someday...

97 coupes (1FP87) came in 3 different specs: 1SA, 1SB, 1SC

97 convertibles (1FP67) came in: 1SD, 1SE, 1SF

97 RS coupes (1FP87) came in: 1SN, 1SP, 1SQ

97 RS convertibles (1FP67) came in: 1SR, 1SS, 1ST

97 Z28 coupes (1FP87) came in: 1SG, 1SH, 1SJ

97 Z28 convertibles (1FP67) came in: 1SK, 1SL, 1SM

40P

40P was a one-year option  for 1994 exclusive to an Arctic White Camaro, Z28, convertible, or convertible Z28. It equipped the car with the exact same white wheels that were used on the '93 Indy Pace Cars. This option was not mentioned in the 1994 Camaro brochure. It is mentioned on pages 13, 15, 17, etc. of the 1994 Ordering Information Guide, and as only being optional for cars that are Arctic White. These wheels are GM part number 12513703 (which is the same part number used for the 1993 Indy Pace Cars (which, as an unrelated sidenote, was RPO code B5A). I know that 317 Camaro Convertibles had RPO 40P from the factory and 1,422 Camaro Coupes had it.

10C

'97 30th Anniversary Edition optional Arctic White leather seats with black and white houndstooth cloth inserts.

'97 30th Anniversary Edition Arctic White leather seats.

1LE

This was a Performance Package for Z28s. It was "Intended for Serious Performance Enthusiasts Only." The package had different equipment and specifications for different years, so I will have to eventually list every year out individually. You cannot make accurate generalizations for every year of 1LE due to the changes that happened every year.

In 1994...

This was a $310.00 option. The dealer invoice amount was $266.60, the dealer price was $257.30, and the list price and MSRP were both $310.00. If you had an automatic, you got GU5 Performance Axle Ratio for a discount ($65.00 vs. $175.00) because you were already paying for the engine oil cooler as part of 1LE.  

This included an engine oil cooler and special handling suspension system* (including larger stabilizer bars, stiffer shock absorbers, and bushings). It required FZAB Base Preferred Equipment Group** and QLC tires. Cars with automatic transmissions had to have GU5 axle***. It was not available with AC3 (power seat) or CC1 (T-top roof panels). 

*=Here are the specific specifications for the 1LE suspension parts for 1994 vs. a regular Z28:

**=FZAB for 1994 included very few options and was the lowest equipment group for a '94 Z28 Coupe.  FZA1 was Preferred Equipment Group 1 and included air conditioning, cruise control, remote hatch release, fog lamps, and engine oil cooler (with manual transmission ONLY). FZA2 was Preferred Equipment Group 2 and included everything FZA1 did, with the addition of power door locks, power windows, power mirrors, leather wrapped steering wheel, transmission shift knob, and parking brake handle, and remote keyless entry. 

***= It's worth mentioning that GU5 automatically gave automatic Z28s an engine oil cooler when the Performance Axle Ratio option was chosen... and that (at least in 1994) all FZA1 and FZA2 manual Z28s already had engine oil coolers (the only ones that didn't were FZAB coupes without 1LE). So the oil cooler was fairly common on '94 Z28s.

In 1995...

This included an engine oil cooler and special handling suspension system* (including larger stabilizer bars, stiffer springs, shock absorbers, and bushings). It required 1SH Base Preferred Equipment Group** and QLC tires. Cars with automatic transmissions had to have GU5 axle*** and could not have YF5 or NG1 emissions. It was not available with AG1 (power seat) or CC1 (T-top roof panels). 

*=Here are the specific specifications for the 1LE suspension parts for 1995 vs. a regular Z28:

**=1SH for 1995 included very few options and was the lowest equipment group for a '95 Z28 Coupe.  1SJ was Preferred Equipment Group 1 and included air conditioning, cruise control, remote hatch release, fog lamps, engine oil cooler (with manual transmission ONLY), and 4-way manual seat adjuster. 1SK was Preferred Equipment Group 2 and included everything 1SJ did, with the addition of power door locks, power windows, power mirrors, leather wrapped steering wheel, transmission shift knob, and parking brake handle, and remote keyless entry. 

***= It's worth mentioning that GU5 automatically gave automatic Z28s an engine oil cooler when the Performance Axle Ratio option was chosen... and that (at least in 1995) all 1SJ and 1SK manual Z28s already had engine oil coolers (the only ones that didn't were 1SH coupes without 1LE). So the oil cooler was fairly common on '95 Z28s.

AAA

I saw this on '02 V6 Firebird 2G2FS22K622151008 and haven't decoded it yet since I haven't seen it on a Camaro yet.

AAT

This RPO code signifies a two-tone (special) paint process done at GM. In most cases, the two-tone paint jobs were simple, as if white doors were put on a black car for example.

Production #s:

1993: 653 (all were Indy pace car replica coupes with 01U paint code)

1994: 0

1995: 0

1996: 50 (all were B4C coupes with 01U paint code)

1997: 0

1998: 15 (all were B4C coupes with 01U paint code)

1999: 0

2000: 10 (all were B4C coupes with 01U paint code)

2001: 0

2002: 13 (all were B4C coupes with 01U paint code)

The majority of two-tone B4C police Camaros were not AAT and were not painted two-tone by GM. Most were painted aftermarket.

Examples of AAT:

2002 B4C with AAT and 01U from the California Highway Patrol

2002 B4C from the California Highway Patrol after being retired from service

2000 B4C (likely AAT, but unverified) from the South Carolina police

1993 Pace Car Replica with AAT

1993 Pace Car Replica with AAT (decals have been removed and exhaust is not OEM nor is the bra)

Examples of B4C that are definitely NOT AAT:

-Florida B4C in black and beige

-Dallas, Texas B4C in black with white hood, roof, hatch (some might have been AAT, but most I have seen have not been)

A26

possibly has something to do with UK and European window glazing... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

A31

power windows (in '93 - '97 this required AU3 and DG7)

A90

power hatch release ('94-'97 this required AU3)

ABN

I'm currently unsure what this one means... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

AC3

power 6-way drivers seat. This code was used for 1993-1994. AG1 was used instead for 1995-2002.

AG1

power 6-way drivers seat

AH3

4-way manual front seat adjuster, driver. This code was definitely used 1993-1999, but I'll need to check for other years.

AK5

front seat driver and passenger airbags

AN4

Child Restraint Provisions for Canadian cars (at least beginning in 1994). I'm not entirely sure what this changed on the car...

AR9

front bucket seats, reclining cloth

AQ9

Trans Am (at least for '93) front bucket seats, reclining-fully articulating sport seats in cloth. I'm including this in case it shows up on exported Camaros, but this is a Trans Am RPO code.

Update: this code does show up on many European export Camaros with Trans Am seats.

AU3

power door lock system

AUO or AU0

remote keyless entry ('94-'96 required AU3, A31, A90). In 1997 this changed to remote keyless entry including Theft Alarm System ('97 required AU3, A31, A90). I believe the alarm was included at some point for '96 though... In 1998 the description changed to remote keyless entry with illuminated interior feature including Theft Deterrent Alarm System. From 1998-2002 there is no mention of other required options in order to have AU0.

AX4

this might have something to do with front and rear seat belts... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

B0G

Vehicle GM Production Week 25. 

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one.

B35

Rear carpeted floor mats. (This may have become a new option in 1995, or just a new option for B4C Camaros in 1995).

B4C

Special Service Package, nicknamed Built 4 Cops.

The B4C information from the 3rd gen Camaros often gets lumped in with the 4th gen info, and that makes deciphering fact from fiction very difficult. I'm going to help with that eventually, but not on this page too much.

For 4th gens, the Camaro Special Service Police Package did not include special equipment options (e.g., spotlamps, wiring, etc.). Things changed from year to year, but for 2001, to order a Camaro Special Service Police Package, you had to order model 1FP87 (a coupe), option B4C, and 1SP Preferred Equipment Group. You can view this old 2001 archive of GM's page about B4C Camaros here, but it does contain errors potentially.

4th gen B4C Camaros from the factory, had very, very, very little different about them than Z28s. For example, don't believe the false information that says that 4th gen B4Cs had beefier alternators than Z28s, because it's absolutely false.

Many of the cars that were put into duty as police cars were modified further by government garages according to one police officer (SpikeLS1 from camaroz28.com). He also stated that they would often change the lid (air intake), MAF, and put on 160 degree thermostats. However, he said that B4Cs could be insured as V6 Camaros, which is not true at all. So take anything you read with a grain of salt.

In the early 2000s (definitely before 2004), Scott Settlemire (fbodfather) had this to say about B4C Camaros on ls1.com (including a bit about 01U as well):

Got this question asked on another board and figured that because the question comes up with regularity, I'd post it here, too.......... (moderators...you may want to move this to other forums.......)

The question: How does a B4C differ from a Z28?

Since 1998, the only real parts difference, overall is the rear trailing arms.

The packaging is different. From 1998 thru 2000, the B4C came with a Power Steering Cooler, whereas the Z28 offered the cooler as an option....however, the cooler was made standard on all V8s in 2001/ 2002.....

From 1998 thru 2000, the B4C included Eagle RS-A Tires..which meant the car was not speed limited to 110 (or thereabouts) as a standard Z28 with the standard Eagle GA tires. (Z28s with RS-A tires or GSCs were speed limited to 162mph as I recall.)

From 1998 thru 2002, the B4C had power windows, locks, mirrors, and driver's seat in the package along with, I believe, fog lamps cruise control, and a power hatch release. (this forces a heavier wiring harness in the body of the car.......) The B4C also came with the vinyl steering wheel and brake release handle unless you specifically ordered the leather wrapped wheel ('98/'99) or the "Duplicate Radio Controls" (00, 01, 02) which got you the leather wrapped wheel and brake release. The B4C also deleted the Z28 emblems and furthermore forced a body colored roof panel, rather than the black roof panel that Z28s came with. CC1 removable roof panels were not available. The 6-speed transmission WAS available. However, from Start of Production in the '98 model year, thru the end of January 2002, the B4C could only be ordered 'Fleet' and that required a 6-digit fleet code to do so. Starting in February of 2002, the B4C was opened up (quietly) to retail orders for a good reason: We told (thru our fleet operations) all B4C users that fleet orders would not be accepted after February 1 due to build out and the large number of sold orders. Naturally, we started getting calls from dealers/police departments wanting to "order one more car......."

No larger battery, no larger alternator, no special transmission or engine or brakes......

oh....a few other things....I believe we made the Monsoon system standard on the Z28 in 1998. (memory is fading...it's late.....) The B4C, on the other hand, got the standard radio ...but could be upgraded to the Monsoon as a free flow option.... and remote keyless entry, while in the upgrade package on the Z28 was a free flow option on the B4C. AND......depending on the number of orders, we would two-tone cars with B4C....required, as I recall, a 90 day lead time and line drawings would have to be submitted.....and the colors had to be existing RPO colors........paint lines would be established by body panels. Most usually had doors and hood the secondary color with the rest of the panels the primary color. There was a charge for this, and thus, most departments desiring special paint would do it locally once they received the cars.

Hope that clears up the mystery...............

Scott S. 

B5A

1993 Indy Pace Car Package. This code required many other RPO codes, because this was the black and white two-tone pace car replica package only available on Z28s. 

Color code 1: 01U
Color code 2: 01U
Graphite interior trim color
Cloth Bucket: CBB3
Special Paint Code 1: 8555
Special Paint Code 2: 9567
Paint Scheme: F010

FZA2 (Preferrend Equipment Group 2) was required. 

B5A included Camaro Z28 standard features in addition to 4-speed auto (MX0), P245/50ZR16 B/W tires, electric rear window defogger, 6-way power driver seat, removable roof panels (T-tops) including locks and lockable stowage provisions), performance axle ratio (included engine oil cooler), Delco/Bose music system with CD player, front license plate bracket.

The only option was emissions, either NA5 (standard emissions) or YF5 (California emissions).

B63

I have no idea what this means right now ... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium as well as a 2000 V6 Camaro exported to Belgium. 

B84

Body side moldings (for taking the abuse of other people's doors hitting the car). 

BAG

Parts package for export. Not sure what exactly this means/is/includes. I need to look at more export cars. This code showed up on a '94 Puerto Rico export car with CW7 and a 1999 V6 Camaro that was exported to Belgium.

BBS

Introduced in 2000, this code was for the Hurst shifter on 6-speed Z28s and SSes.

BDA

Pre-Pilot Vehicle Identification. Seen on perhaps only 6 1995 coupe Z28s.

BMA

Production Trial Run Identification. First seen on perhaps only 6 1994 convertible Z28s. In 1995 it was seen on 9 coupe Z28s and 3 convertible Z28s. In 1996 it was seen on 3 SS coupes with R7T. 

BZ0

This code means Vehicle GM Production Week 09. I don't know why this code exists to be honest. 

I've also seen this code on one of the 2002 sebring silver Indy 500 convertible Z28 festival cars (no, not one of the Z7D SSes, one of the Z28s, though the SSes might have it too...).

C1U

Fleet incentive - Enterprise Rent-A-Car (B/C/D/E/F/H/J/K/L/N/U/W TRK CKGMLPST)

There were 2,984 1997 model year Camaro convertibles with this code, and they were sold to Enterprise to be used as rent cars. There were 200 1997 model year Camaro coupes with this code as well. 

For 1996, 1000 Camaro convertibles were built for Enterprise.

C41

Heater only, no Air Conditioning.

C49

Electric rear window defogger

C60

Air Conditioning.

Fun fact: in 1994 this was a $895.00 option. The dealer invoice amount was $769.70, the dealer price was $742.85, the list price and MSRP were both $895.00.

C9C

Special black roof treatment. This required T-tops in 1993 for V6 Camaros, but was standard on Z28s that year. To keep this simple... if you have C9C and T-tops, your car had a black C-pillar when new. I'll fill in detailed for other years eventually.

CAE

This code indicates a handling charge for delivering the car to SLP's LaSalle facility for conversion. It likely does not appear on any '96 SSes at all, but it appears on many '97 SSes. It also appears on '96 RSes and '97 RSes. Some '97 RSes have WT4 instead. It also appears on a very large number (perhaps all) of the '98-'02 SSes.

CC1

T-tops. 

The design was different in 1994 from other years (i'll have to investigate 1993). In 1994, there were no shades included and the glass was covered in a frit pattern. 1995 T-tops were clear with Velcro dots that held removable covers.

For many years (certainly including 1993), CC1 also made a black roof treatment standard on V6 Camaros (which was RPO code C9C).

Also, the only way to calculate the number of hardtops produced is to subtract the number of CC1 (T-top) cars from coupe production numbers. There's not an RPO code for hardtop.

1994 T-tops

1995 T-tops

D21

This might have something to do with a sunshade windshield for exported cars... like tint at the very top of the windshield... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

D35

Manual passenger side mirror and driver mirror with a manual joystick. The technical terminology for this is outside lefthand remote mirror, righthand direct mirror. The appearance of these mirrors is the normal US/Canada side mirrors.

D5R

Gear, speedometer driven. I'm not 100% sure what this means, but I believe it will typically be paired with D8M (if the car has a manual transmission... at least). I'll need to verify that. I saw it on a 1993 V6 Camaro with 5 speed manual transmission. 

D82

Coupe with monochromatic paint. This means the car was ordered to have a body colored roof and mirrors. It was a "no cost" option. This applied to both hardtop and T-top coupes regardless of engine. It first began in 1995 and V6 Camaros had to have T-tops to have it, while Z28s could have it with a hardtop or with T-tops. The last year this option was available was 1997.

Specific to 1997 (and not possible to necessarily generalize to earlier years): The '97 ordering guide states that D82 required CC1 (T-tops) for V6 and V6 RS coupes. Z28s could have D82 with a hardtop or T-tops. A black Camaro/RS/Z28 would not need D82, because it is already monochromatic, and yet, you can sometimes (always?) see black ones with D82.  D82 wasn't available on convertibles. Black mirrors weren't available on Z28 convertibles for this year.  Black mirrors were standard equipment on Z28 coupes and RS coupes (with T-tops) only, according to the 1997 order guide. I have seen black mirrors on V6 Camaro coupes with T-tops as well, however, I only have pictures of 1 car in my photo collection. V6 Camaro coupes were not specifically mentioned in the order guide regarding the color of their mirrors if T-tops were specified.  If a V6 coupe or V6 RS coupe had a hardtop, they'd have a body colored roof automatically. If they had T-tops, they would come with a black C-pillar standard. The V6 Camaro coupes would (apparently) come with body-color mirrors and the V6 RS Camaro coupes would come with black mirrors. Like I said above, the base model V6 Camaro coupes with T-tops were not mentioned specifically in the order guide regarding their mirror color, however they came with black mirrors. 

D8M

Vehicle speed sensor. This is specific to 1993-1995 3.4L V6 Camaros/Firebirds with 5-speed manual transmissions. I believe it will typically (always?) be paired with RPO code D5R. Just because this came up in my research: The replacement GM part number for this speed sensor is 10456087; ACDelco part number 213-196 (discontinued for the U.S. market since August 1, 2011, and is discontinued for Canada market since February 28, 2009). I saw this RPO code on a 1993 V6 Camaro with 5 speed manual transmission. 

DC4

inside rearview mirror with dual reading lamps (operates by opening door or by switch)

DD9

These are the side mirrors put on Japanese export Camaros as well as some/most/all European export Camaros. These mirrors are sometimes referred to as paddles, because they fold inward. They are also sometimes referred to as breakaway, because if another vehicle hits them, the mirror will break off and hopefully not damage the rest of the car.

DE4

Removable sunshades for the t-tops. 1995-2002. This code will always be paired with CC1 (T-tops) for these years.

DG7

Twin remote electric mirrors (in '93-'97 this also required AU3 and A31). The appearance of these mirrors is the normal US/Canada side mirrors.

DL5

Roadside service information decal.

DT2

I'm unsure what this means. One definition of it says "Delete Document Customer Reference" which is... strange. I saw this code on a manual 2001 V6 Camaro Convertible exported to Belgium.

E2C

Rapid Delivery System Custom Orders. An order to expedite the delivery to the customer. 

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. I've also seen this code on one of the 2002 sebring silver Indy 500 convertible Z28 festival cars (no, not one of the Z7D SSes, one of the Z28s, though the SSes might have it too...).

It's also been seen on a B4C.

EGW

Delayed Warranty Start. Sometimes called Fleet Incentive C.O. Fleet Approval Required. Sometimes called "Delayed Warning" which is a really weird way to write it.

I saw this on a 2001 B4C, so it might be common to B4C cars. If so, it's likely correlated with the police adding additional equipment to the car, and waiting to put it in service until it is finished and ready to be driven.

The "C.O." could mean so many things, but I believe it means "Company Owned" in this case.

EXP

This is the code specific to exporting the car overseas (out of North America). It's technically "Export I.E.S." I have no idea what IES means and I cannot find an explanation. My guess would be International Export Service. This code may be what orders specific market equipment (but I kind of doubt it, since that would be country-specific). This code appears on Puerto Rican exported cars and likely others. This needs more research.

I believe for 1993, all EXP Z28 cars were destined for Japan. 

F67

This is the weather stripping for the convertibles.

F87

This is the weather stripping for the coupes.

FCAB

In 1993, this was a V6 Camaro Coupe (1FP87) with "Base Preferred Equipment Group", in other words, a Camaro with "Standard Equipment." This included a 3.4L engine, 5-speed manual, P215/60R16 B/W tires, 16" steel wheels with bolt on covers, AM/FM stereo radio with seek/scan, digital clock, stereo cassette tape, search, repeat, extended range speakers, gauge package with tachometer and dome lamp. 

Other standard equipment this year included a driver and passenger air bag system, 4-wheel anti lock brake system, front disc and rear drum power brakes, brake-transmission shift interlock (automatic transmission only), PASS-Key II Theft Deterrent System, energy-absorbing front and rear 5 mph bumpers with body-color fascias, integral rear spoiler, 4-wheel coil spring suspension system with computer-selected springs, short-long arm front suspension system, power rack and pinion steering, front and rear stabilizer bars, monotube shocks front and rear, stainless steel exhaust system, single serpentine belt accessory drive, compact high pressure spare tire, base-coat/clear-coat paint, black dual sport mirrors (lefthand remote, righthand manual), miniquad halogen headlamps, tinted glass, solar-ray glass, check gauges warning light, low oil level indicator system, headlamps-on reminder, comfortilt steering wheel, intermittent wipers, side window defoggers, center console with cup holder and lighted storage compartment, storage compartment in doors, lefthand and righthand covered visor mirrors, day/night rearview mirror with dual reading/courtesy lamps, driver's side 4-way manual seat adjuster, full floor carpeting, carpeted cargo area, closeout panel for cargo compartment area, front floor mats, Scotchgard Fabric Protector (includes seats, door trim, and floor covering), cloth reclining bucket seats with integral head restraints, full folding rear seat back.

To order a '93 B4C, you had to select FCAB and add B4C to it. Weird, I know.

FCA1

In 1993, this was a V6 Camaro Coupe (1FP87) with "Preferred Equipment Group 1" which included "Base Preferred Equipment Group", Air Conditioning, Electronic Speed Control with Resume, Remote Hatch Release, and Fog Lamps.

FCA2

In 1993, this was a V6 Camaro Coupe (1FP87) with "Preferred Equipment Group 2" which included "Base Preferred Equipment Group", Air Conditioning, Electronic Speed Control with Resume, Remote Hatch Release, Fog Lamps, Power Door Lock System, Power Windows with Driver's Side Express Down Feature, Sport Dual Remote Electric Mirrors, Leather Wrapped Steering Wheel - Transmission Shifter - Parking Brake Release Handle.

FLT

Fleet Processing Option.

Fleet orders confuse me, so I will never be an authority on them, but here's my understanding of them, particular to the year 2001.

Fleet described a type of customer that made multiple purchases and operated a sizable "fleet" of vehicles. Specifically, a qualified fleet customer was defined as any company that purchased or leased five or more new vehicles solely for use in its operations during the current or preceding model or calendar year. In addition, a customer may also have qualified if they owned or leased fifteen or more vehicles. All political subdivisions and public utilities automatically qualified as Fleet customers. 

Once a customer was "qualified" as a fleet customer by a GM Dealer, the dealer would apply for a customer specific fleet account number (FAN). The FAN was universal - i.e. the same number could be used for all GM products. The FAN was assigned to a particular customer and remained in effect as long as the customer met the fleet volume requirements. The FAN was utilized by all divisions of GM to process orders, track vehicle production and identify those customer who may be eligible for fleet incentives in conjunction with the purchase or lease of new GM cars and trucks. 

In 2001 and 2002 (maybe other years too) there was a Fleet Purchase Program for rental, commercial, commercial leasing, and political subdivisions (VX5) in the United States, but I don't think this program could be used for Camaros. In 2001, Camaros were not on the list of vehicles. This particular program offered allowances to General Motors dealers and qualified fleet customers on select new and unused General Motors vehicles sold and delivered to qualified rental, commercial, commercial leasing, and political subdivision fleet customers/users in the United States.

What about B4C Police Camaros (which often (always?) have the FLT RPO code? 

Well, you can read more on this 2001 archive of GM's Fleet page for the Special Service Package Camaro. It does not contain any particularly important information, except that it shows that Camaros were put into a "Specialized Vehicles" category specific to Law Enforcement. Evidently, in 2001, Camaros were no longer possible to purchase at a fleet rate based on this and other 2001 archives of GM websites. 

Do take note, that in 1996 and 1997, Enterprise rent-a-car did in fact have Camaros as part of their fleet and even had an RPO code 100% specific to them:  C1U. I'll have to look on my computer with that car saved to it, and see if it had the FLT RPO code or not.

FZAB

In 1993, this was a Z28 Camaro Coupe (1FP87) with "Base Preferred Equipment Group", in other words, a Camaro Z28 with "Standard Equipment." This included a 5.7L engine, 6-speed manual, P235/55R16 B/W tires, 16" aluminum wheels, AM/FM stereo radio with seek/scan, digital clock, stereo cassette tape, search, repeat, extended range speakers, limited slip rear axle, gauge package with tachometer, ride and handling suspension, dome lamp, special black roof treatment, and front and rear power brakes with ABS.

Other standard equipment this year included a driver and passenger air bag system, 4-wheel anti lock brake system, power front and rear disc brakes, brake-transmission shift interlock (automatic transmission only), PASS-Key II Theft Deterrent System, energy-absorbing front and rear 5 mph bumpers with body-color fascias, integral rear spoiler, 4-wheel coil spring suspension system with computer-selected springs, short-long arm front suspension system, power rack and pinion steering, front and rear stabilizer bars, monotube shocks front and rear, stainless steel exhaust system, single serpentine belt accessory drive, compact high pressure spare tire, base-coat/clear-coat paint, black dual sport mirrors (lefthand remote, righthand manual), miniquad halogen headlamps, tinted glass, solar-ray glass, check gauges warning light, low oil level indicator system, headlamps-on reminder, comfortilt steering wheel, intermittent wipers, side window defoggers, center console with cup holder and lighted storage compartment, storage compartment in doors, lefthand and righthand covered visor mirrors, day/night rearview mirror with dual reading/courtesy lamps, driver's side 4-way manual seat adjuster, full floor carpeting, carpeted cargo area, closeout panel for cargo compartment area, front floor mats, Scotchgard Fabric Protector (includes seats, door trim, and floor covering), cloth reclining bucket seats with integral head restraints, full folding rear seat back, low coolant level indicator system, platinum tip spark plugs.


FZA1

In 1993, this was a Z28 Camaro Coupe (1FP87) with "Preferred Equipment Group 1" which included "Base Preferred Equipment Group", Air Conditioning, Electronic Speed Control with Resume, Remote Hatch Release, and Fog Lamps.

FZA2

In 1993, this was a Z28 Camaro Coupe (1FP87) with "Preferred Equipment Group 2" which included "Base Preferred Equipment Group", Air Conditioning, Electronic Speed Control with Resume, Remote Hatch Release, Fog Lamps, Power Door Lock System, Power Windows with Driver's Side Express Down Feature, Sport Dual Remote Electric Mirrors, Leather Wrapped Steering Wheel - Transmission Shifter - Parking Brake Release Handle.

FE9

Federal emission requirements (no charge).

GAM

Government Vehicle. Seen on 26 Z28 coupes in 1995. I wish I knew more...

GU2

This is the standard axle ratio for an automatic Z28. The ratio is 2.73. 

With this axle ratio, you do not have 1st gear as a selectable option on your shift plate. 

This is due to federal noise pollution regulations GM had to conform to. Cars with RPO GU5 have 1st gear, because their 3.23 ratio made 1st gear impossible to select. Why? Because the speed was too high for a 3.23 Z28 to run in 1st gear (speed would have been higher than redline RPM), but not too high for a 2.73 Z28 to run. The 2.73 Z28s would be too loud (high in RPM) to pass the test in first gear, so GM had to restrict it. 

I don't remember the 4-speed automatic gear ratios off the top of my head, so I can't tell you what speed the test was testing, but I would "assume" it was 45 mph. 3.23 axle would likely cause the max speed in 1st to be closer to 40, while 2.73 would likely cause the max speed in 1st to be closer to 50. I need somebody to do the math...

GU5

This is a performance axle ratio for a Z28 or SS with automatic transmission. The axle ratio is 3.23, which is what the manual 6-speed Z28s in 1993 had for axle ratios. 1994 to 2002 6-speed Z28s came with 3.42. To be technical, and add confusion, the rear axle ratio on all '93 V6 Camaros was 3.23 and GU5 whether it had a M49 (manual) or MX0 (automatic) transmission.

With regard to SS, GU5 was absolutely required as part of the package if you chose an automatic transmission.

With this package, you would get 1st gear selectable on the shift plate, and it was the only way to get it with 1st gear shown as selectable from 1994 til 1996.

Production #s:

GU6

3.42 rear axle ratio with a torque rating up to 450 lb/ft. This is normally associated with manual transmission equipped V8 Camaros. It's also seen on all V6 automatic Camaros with Y87. I'll add more detailed information regarding this code in the future.

G80

Positraction (limited slip) differential.

G92

This is the optional performance axle ratio for 1993 automatic AND manual Z28s. The axle ratio is 3.23 just like GU5. You were required to have QLC tires and C60 air conditioning. This option also included an engine oil cooler. In 1993, G92 is what got your car the 150 mph speedometer as well (instead of the 115 mph one). For 1993, G92 includes GU5, KC4, QLC, and either M29 (manual) or MD8 (automatic).

Production #s:

1993: 14,428

IL4

This has something to do with the interior... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

IP2

Leather interior trim.

IPB

I saw this on '02 V6 Firebird 2G2FS22K622151008 and haven't decoded it yet since I haven't seen it on a Camaro yet.

J1F

Supposedly this is Special Brakes for Exported models or "Special Brake Provisions to Suit Foreign Regulation", but I see it on '95 Z28s and B4Cs I've looked at. In fact, it appears on 99,371 '95 Z28 coupes, so it can't be for exported models as it isn't rare enough. More research is needed.

I have seen it on a '95 3.8L V6 Canadian coupe as well. It also had J41, so it definitely had rear drum brakes still.

J41

Power Brake System with front disc brakes and rear drum brakes. This was standard on V6 Camaros for many years.

J65

Power Brake System with 4 wheel disc brakes.

JAF

This might have something to do with brake provisions for Europe... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

K05

Engine block heater.

Sorry, but I do not remember who supplied me this photo of their engine block heater cord. Happy to add credit if you email me.

Photo from Mike M of his 2002 SS's engine block heater cord. According to Mike, it has never been uncoiled or used.

K29

Powertrain Control Module (for Export?)

Not 100% sure why the PCM is different for Canadian models, but it seems to be... at least for '96-'97. This will need more investigation.

Witnessed on a '96 Z28 Canadian coupe with manual transmission.

Witnessed on a '97 Z28 Canadian 30th Anniversary Edition Z4C coupe with automatic transmission (3,870 '97 coupe had K29). 

Witnessed on a 1999 V6 Camaro that was exported to Belgium with an automatic transmission as well as a '00 V6 Camaro, automatic, for Belgium. 

K34

Cruise control, a three-mode type with resume feature. (electronic speed control with resume and it required T96 fog lamps in '93-'97).

K43

102 Amp generator, 12V

It's the LS1 alternator from '98-'02 for Z28s, B4Cs and SSes. I don't currently know why the LS1 cars had much lower amp alternators than LT1 cars. I'll research it in the future. 

GM Part # 10464402 for 1998. GM Part # 19152060 (which was replaced by 19244783) for 1999-2002 I believe.

1998-2002 B4C cars definitely had the same generator as Z28s.

K68

105 Amp generator (alternator) on V6 Camaros exclusively. 12V.

Used on '93-'02 V6 Camaros with L32 and L36 V6 engines.

The GM part number was different for '93-'95, '95-'97, '98, '99, and '00-'02... so that's fun. They were all 105 Amps and K68.

I've also seen K68 on two '98 Canadian Z49 Z28 coupes, so that's an interesting twist. I've yet to dive in to whether or not the generator is truly 105 amps for these Canadian Z28s... so more research is needed.

KC4

Engine oil cooler. This was included in the G92 package in 1993 and all cars had GU5. I'll add more info for other years eventually. I also saw this on a '94 Puerto Rican export Z28 with GU5 and a '95 Z28 with GU6 and MN6. Needs more research...

KG7

125 Amp generator (alternator) (at least for 1993, for other years, I'm not yet sure if KG7 was available or not... I don't think it was). It's what Camaro Z28s and B4Cs (with an LT1 engine) had. 12V.

The technical specs for this one say it's actually 124 amps. For '93 it's definitely GM part #10463446.

1993 B4C cars definitely had the same generator as Z28s.

KG9

140 Amp generator (alternator), 12V.  (For '94-'97 Z28s and B4C).

I believe this is GM Part #10463680.

1994-1997 B4C cars definitely had the same generator as Z28s.

L32

The 3.4L V6 available in the 1993 to 1995 Camaros.

L36

The 3.8L V6 made available in 1995 (late in the model year). Initially, this engine only appeared in Camaros destined for California, who had high emission control standards. For 1995, this engine was only available with an automatic transmission and only appeared in 4,787 Camaros that year. These '95 cars will also feature YF5 Emissions, only, and were required to have C60 (air conditioning); however this might only be specific to US models. The '95 3.8L V6 Canadian Camaro coupe I found (built 6/6/1995) had FE9 emissions. 

From 1996 to 2002, this engine was the only V6 available and it was available with an automatic or a 5-speed manual transmission.

LT1

The 5.7L V8 (350 CID) engine available from 1993 to 1997 in Z28 and B4C Camaros.

LT4

There were 106 LT4 1997 30th Anniversary Edition SS hardtops built, however, not a single one (nor any other '93-'02 Camaro) has an LT4 RPO code on the RPO code sticker. All of the LT4 cars have LT1 on their RPO code sticker. The LT4 was put in the car by SLP. Identifying one of the LT4 cars is most easily done via the LT4 emissions label on top of the radiator shroud. The passenger door should also have an SLP sticker stating the LT4 SS number (if it is still readable; SLP's ink fades over time).

M28

It has something to do with the 6-speed manual transmission on a '93 Z28 and B4C. I'll have to research it. The alternative is M29.

The gear ratios were

And since it was associated with GU2, the rear axle ratio was 2.73 with a torque rating up to 360 lb/ft.

Not many manual '93 Camaros have this. 0 B4C, 701 Z28s.

M29

It has something to do with the 6-speed manual transmission on a '93 B4C (as well as Z28). I'll have to research it. The alternative is M28, which you'll find exclusively on '93 Z28s.

The gear ratios were

And since it was associated with GU5, the rear axle ratio was 3.23 with a torque rating up to 400 lb/ft.

Most manual '93 Camaros have this. 28 B4C, 3428 Z28s.

M30

It means "4-speed automatic" while MX0 means "transmission provisions for an automatic". It is seen on '94-'02 V6, Z28, and B4C Camaros. 

This transmission was the 4L60-E, and it had electronically controlled shifting. The PCM (Powertrain Control Module) told it when to shift. This RPO code replaced the 1993 MD8, and that older transmission was the 4L60. 

M49

5-speed manual transmission for V6 Camaros (at least for '93 and '94)

MAE

This might mean Marketing Area Europe for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

MD8

It means "4-speed automatic" while MX0 means "transmission provisions for an automatic". It is seen on '93 V6, Z28, and B4C Camaros. It was available in 1993 with GU2 or GU5.

This transmission was the 4L60, and it did not have electronically controlled shifting. This RPO code was replaced in 1994 with M30, and that transmission was the 4L60-E.

MM5

5-speed manual transmission

MM6

Introduced in 1994 and used through 2002, this was the 6-speed manual transmission that replaced both M28 and M29 from 1993.

It included CAGS (Computer-Aided Gear Selection) which was the "Skip Shift" annoyance (I mean feature).

The gear ratios were

And since it was associated with GU6, the rear axle ratio was 3.42 with a torque rating up to 450 lb/ft.

MN6

6-speed manual transmission. For 1993, it technically means "transmission provisions for a manual" and is associated with M28 and M29.

MX0 or MXO

4-speed electronically controlled automatic transmission with overdrive. For 1993, it technically means "transmission provisions for an automatic" and is associated with MD8.

N36

This was the sport steering wheel in base model Firebirds and Formulas (in at least 1993). I imagine it is simulated leather. The Trans Ams that year had NP5. I'm including this in case it solves a future mystery.

N92

Bolt on wheel covers (hubcaps) for steel wheels. Standard on V6 Camaros. Accompanied by QB3 wheels and QEA tires. Painted in Silver Metallic (9021).

N96

16x8 inch silver painted aluminum wheels. These were the Z28 wheels. 

The '93-'96 "salad shooter" wheels were painted Bright Silver Sparkle (9967) and featured carryover hub caps from 3rd gen wheels.

N98

16" chrome aluminum wheels

NA5

According to the '93 ordering guide, NA5 was Standard Emissions. Federal Emissions FE9 must not have existed yet. I witnessed this code on a '94 Puerto Rican exported Z28 and '95 Z28 as well.

NA7

This might have something to do with a European Emission System... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium as well as a '99 Z28 exported to Belgium.

NB8

In 1994, this was California/New York emission override (no charge) and required FE9. In 1998, this was California/New York, Massachusetts, Connecticut emission override (requires FE9).

NC1

California emission requirements, Low Emission Vehicle, for certain years (at least the year 2000). NG1 MIGHT be required with this one. I'm unclear on some things about this code, and it needs more research.

NC7

Federal emission override (no charge) required YF5 or NG1.

NT3

This has something to do with European emissions, but I don't know exactly what it means yet.  I saw this code on a manual 2001 V6 Camaro Convertible exported to Belgium.

NF2

Federal emissions Tier 1. It's seen on a very large number (possibly all) of American and Canadian 1996 to 2000 Z28s/SSes. It might appear on others, but I'd need to do more research to know for sure.

I saw it on a '95 3.8L V6 Canadian coupe Camaro that had FE9 as well.

NF7

Emission System Federal, NLEV (National Low Emission Vehicle). 

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes but did have this one.

NG1

In 1994, this was New York State emission requirements (no charge). In 1998, this was New York, Massachusetts or Connecticut emission requirements. I need to do more research. In 2000, this was available as an option for B4C cars and it is simply called Northeast States Emissions. 

NG5

Fifty state registration emission certification (seen on a '97 V6 Camaro that also had NF2). Needs more research.

NK3

Simulated leather steering wheel (this was the steering wheel w/o leather wrapping)

NP5

Leather wrapped steering wheel, shift knob, and brake release handle. In the 2002 B4C brochure, it mentions this is a leather wrapped steering wheel with redundant radio controls (requiring UL0 or UN0 radio), and it also included leather wrapped transmission shifter and parking brake release handle. This might be incorrect info, because normally that is UK3 (introduced in 2000), and according to the same 2002 B4C brochure, UL0 is not mentioned anymore and was replaced by U27... so that's odd. NP5 was also a leather wrapped steering wheel on (at least) 1993 Trans Ams, so that's another fun detail.

NP7

This has something to do with a steering column on an exported car... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

It's worth mentioning that these European Export Camaros have a much different looking hazard button/switch than US-spec Camaros. It appears to be the same as the 1994-1999 Cadillac Deville/Seville/Eldorado one. The plastic on the ignition cylinder (where the key goes in) is different from US-spec Camaros as well.

NW9

Acceleration Slip Regulation (ASR), GM's jargon for traction control. This became an available option in 1995 on Z28s and B4Cs. GM recommended QFZ tires for optimum traction. Specific to 1995 (and not necessarily applicable to other years) you absolutely could not have NW9 if you had the 1LE Performance Package. That rule may or may not be applicable to other years of 1LE, but it's true for 1995.

P05

Chrome-plated Aluminum Wheels (on a Firebird, Formula, or Trans Am).

PBT

Temporary hood, wheels, and tires for upfitter delivery. This will be seen on most, if not all, 1998-2002 Camaro SSes. It might be seen on some 1996-1997 SSes, but I haven't seen it on one yet.

PDC

Control Sales Item No. 120. This may (or may not) have something to do with a security package on Firebirds.

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. I've also seen it on '02 V6 Firebird 2G2FS22K622151008.

PDN

Control Sales Item No. 131. This may (or may not) have something to do with a power package on Firebirds.

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. I've also seen it on '02 V6 Firebird 2G2FS22K622151008.

PE0

White '97 30th Anniversary Edition 5-spoke wheels. They were 16x8 aluminum wheels that were painted white.

PW7

The 2002 B4C brochure claims this is 16" chrome aluminum wheels, but normally that would be N96, so that's a bit odd. It also appears in the 1993 order guide as 16x8 cast aluminum wheels, but for Firebird Formulas and Trans Ams.

QA7

These are V6 base model Firebird wheels (at least in 1993) that are 16x7.5 cast aluminum. I don't think there's a Camaro connection.

QB3

Standard 16x7.5 inch steel wheels. Accompanied by N92 wheel covers and QEA tires for most years. In 1993, QPE tires would be included with QB3.

QBE

I am only including this one, because a page in the '93 order guide mentions QBE instead of QB3. Standard 16x7.5 inch steel wheels. Accompanied by N92 wheel covers and QEA tires for most years. In 1993, QPE tires would be included with QB3. 

QCB

Standard tires for a Z28, but you did not get the 155 mph speedometer with these standard tires. (Tires, P235/55R16 Blackwall 96T). 

This was also the RPO code (and tires) you'd have to have if you wanted a V6 Camaro with the Y87 Performance Handling Package. On a V6 Camaro, you also had to have N96 (16 inch aluminum wheels) to get these tires.

V6 Camaros without QCB would end up with 16 inch steel wheels with hubcaps and P215/60R-16 Blackwall tires.

QEA

Standard P215/60R-16 Blackwall all season 94T tires for V6 Camaros. Accompanied by N92 wheel covers and QB3 wheels.

QFK

P275/40 ZR-17 s/b radial b/w tires. This code was seen on a 2002 35th Anniversary Edition SS.

QFZ

Introduced in 1995, this code was for all-season performance tires on a Z28. (Tires, P245/50ZR16 Blackwall all-season (optional w/ Z28)). It was supposedly made available to compliment NW9 (traction control).

QG4

Machine faced SS wheels, 17 x 9. This code indicates 2002 35th Anniversary Edition SS wheels.

QII

This might have something to do with some European (?) Export tires, possibly P215/60R16 BW R/PE ST TL AL3 94H... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

QLC

Summer performance tires on a Z28. (Tires, P245/50ZR16 Blackwall summer performance (optional w/ Z28)). In 1993, these were the only optional tires for a Z28 and if you had an automatic, you'd have to have G92 to get them. In 1993, and maybe other years, these were Goodyear Eagle GSC tires.

QMT

Tires, P235/55R16 Blackwall Touring Tires and required N96 wheels. Optional tires for a '93 V6 Camaro, standard tires for '93 Z28; QCB did not exist in 1993. For 1993, and maybe other years, these were Goodyear Eagle GA tires.

QPE

Standard P215/60R16 Blackwall Touring Tires for '93 V6 Camaros. For 1993 (and maybe other years) these were Goodyear Eagle GA tires. Accompanied by N92 wheel covers (though I don't think N92 had to be on '93 V6 Camaros since it isn't in the ordering guide) and QB3 wheels. I think QB3 for this year may have included the wheel covers.

R6D

Control Sales Item No 4: GM Bid Assistance for ordered vehicles.

This appears on several B4C cars I've looked at. In short, it means that a governmental agency applied for a big discount on the purchase price of the car when purchasing it. 

It seems like this code shows up on cars with either VQ1, VQ2, or VQ3 as well.

Ordered units used incentive code R6D.
Units taken out of stock used incentive code PBS. (I'd be curious to see if there's a single Camaro with a PBS RPO code... because in theory, this code would not appear on an RPO code sticker).

I was able to figure it out, but based on a document from 2016 (so... significantly newer than 4th gens... so it's not 100% reliable.) R6D shows up on cars that were ordered by Chevy (and other GM) dealerships that were bidding on state or local government contracts involving the sale of new cars and trucks to eligible customers. Essentially, it was an incentive to get governmental agencies to order cars through that dealership so that dealership would earn more sales (and money) via large orders from these entities, and the entities would get a good discount on buying the cars they ordered. 

Government Bid Assistance enabled GM dealers to demonstrate "corporate citizenship" by providing discounted vehicle pricing exclusively to eligible state and local government agencies. Vehicles purchased under this program would be delivered, registered and titled in the name of the eligible governmental agency. Vehicles purchased with bid assistance had to remain in customer service for a minimum of 6 months. Bid assistance was available to customers falling into any of the following categories: Federal agency, State agency, County agency, City agency, Town, Township, Village, Municipality, Indian Tribe or Nation (excludes casinos), Public Education System, Government-owned/operated utilities, Government-owned/operated railroads. Eligible customers may include volunteer or private fire departments, ambulance companies and transportation companies that provide public services. Eligible customers may include railroad police and college campus police when the jurisdiction of these entities extends into the public sector (surrounding communities and public roads). Police officers, constables, deputies, sheriffs, game wardens and fire fighters who are provided funding in the form of a vehicle purchase allowance by an eligible government agency for the purpose of purchasing and registering an approved vehicle SOLELY in their name may be eligible for bid assistance. Duties of these individuals must include jurisdiction for law enforcement and/or public safety as an extension of the government agency they serve. Dealer will apply for bid assistance using the FAN of the individual’s bid-eligible government entity. Vehicles may be registered in the name of the individual.

R6F

Control Sales Item No 6. I have no idea what this one is.

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. I've also seen this code on one of the 2002 sebring silver Indy 500 convertible Z28 festival cars (no, not one of the Z7D SSes, one of the Z28s, though the SSes might have it too...).

R6M

Introduced in 2000, this code was required on all vehicles ordered by New Jersey dealers. It was known as the New Jersey cost surcharge (sometimes called the surface for warranty enhancement (?). How this enhanced the warranty, I have no idea, and I've had no luck researching the meaning 20 years later.) It was a $93 mandatory option charged to 729 2000 buyers, 464 2001 buyers, and 789 2002 buyers in New Jersey. According to the book The Complete Book of Chevrolet Camaro, 2nd Edition: Every Model Since 1967: With this code "the state of New Jersey fattened their state coffers with schemes to extract more money from taxpayers, and new vehicle buyers weren't spared." However, this book has known issues with reliability (incorrect/inaccurate info at times), so that may just be the author's opinion. According to that author, this code was introduced in the 2002 model year, but it was introduced in 2000. His book is about 1967-2002 Camaros, and he clearly was not a 100% expert in 4th gens, so the book's claims can be inaccurate.

R6P

Control - Sales Item No.15. 

I don't know what this means yet, but it is found on all 7 of the last 2002 Camaros and Firebirds to come off the production line. More research is needed.

R6V

This code doesn't pertain to Camaros at all. It is the code for a '93-'97 SLP Firehawk. This isn't a Firebird website, but I will add this: For 1996 R6V required QLC, K34, GU5 (for automatic cars only), and hardtop and t-top models required T43 (uplevel spoiler). I don't know the requirements for the other years.

R6Z

Control - Sales Item No. 25. Drop ship to SLP Canada. This identifies Canadian 4th gen Firehawks and Camaro SSes. I will need to study this RPO more to see if it actually appears on many/all Canadian SS cars. So far, I don't think it does. I don't want to make claims about which years it was on cars until I figure that out.

R7A

Control Sales Item No. 26. It's the Genuine Customer Care Package, which included: 

"* no deductible bumper- to- bumper 3 year/36,000 mile limited warranty * 24 hour roadside assistance * courtesy transportation at participating dealers * "scotchgard" protector * see dealer for details."

R7G

Control Sales Item No. 32. NAO CVEP Identifier. I believe those abbreviations stand for North American Operations Company Vehicle Evaluation Program, so it's an identifier of that. Meaning that the car was driven by a GM employee for a time period before it was sold.

It appears on all 49 of the '97 Brickyard 400 festival cars (the ones without Hugger Orange stripes). Supposedly all of the August 2, 1997 festival cars had 1AA and R7G.

R7I

Control Sales Item No. 34. I've seen this on two '96 Canadian SSes. More research is needed, because I cannot find any information about what this code means for a '93-'02 Camaro. The SSes I saw it on did not have R7T (but did have WU8), so perhaps R7I has something to do with a Canadian SS for this particular year.

R7K

Control Sales Item No. 36. Missing Option Credit... or... Special Option Processing.

This may have something to do with some Canadian Camaros, but more research is needed. It might have something to do with a credit back to the dealership for a missing component in an option package (due to it not being available for Canadian Camaros)... or it might have something to do with special option processing. Again, more research needed. I also witnessed this on a '94 Puerto Rican export Z28, a '98 Z28 Canadian coupe, a '99 Belgium export Z28, a '95 3.8L Canadian coupe, and a 1999 Belgium export V6 Camaro coupe.

R7M

Control Sales Item No. 38, which is Vehicle Invoice Credit... or... Dealer Invoice Credit.

I've seen it on a '94 V6 coupe (built 9/20/1993, and it did not have R7K, but had 1AZ) and 17,402 other '94 coupes had R7M that year. Unlike the others (see below), this car did not have Z31 or Z49.

I've also seen it on a '96 Z28 coupe for the Canadian Market (Z49) (built 9/21/1995, and it also had R7K). This car lacked codes I recognize that differentiate dealership stock orders vs. customer ordered vehicles, so this car didn't have 1AY, 1AZ, R9Z, SLL, or SLM. It did have Z31, which means Preliminary Invoice or Price Sheet Advance. It's possible that Canadian market cars lack these normal codes or use Z31 instead.

I've seen it on a '97 30th Anniversary Edition Z28 Canadian coupe (1,503 other coupes that year had R7M as well... coincidentally the same number of R7K were made that year too, and this car had R7K as well.) I didn't get the VIN, so I don't know its build date. This car lacked codes I recognize that differentiate dealership stock orders vs. customer ordered vehicles, so this car didn't have 1AY, 1AZ, R9Z, SLL, or SLM. It did have Z31, which means Preliminary Invoice or Price Sheet Advance. It's possible that Canadian market cars lack these normal codes or use Z31 instead.

I've seen it on a '98 Z28 Canadian Market coupe (built 8/22/1997) that had both R7M and R7K as well as Z49. This car lacked codes I recognize that differentiate dealership stock orders vs. customer ordered vehicles, so this car didn't have 1AY, 1AZ, R9Z, SLL, or SLM. It did have Z31, which means Preliminary Invoice or Price Sheet Advance. It's possible that Canadian market cars lack these normal codes or use Z31 instead.

A '98 Z28 Canadian coupe built 10/30/1997 with R7M, R7K, and Z49. This car lacked codes I recognize that differentiate dealership stock orders vs. customer ordered vehicles, so this car didn't have 1AY, 1AZ, R9Z, SLL, or SLM. It did have Z31, which means Preliminary Invoice or Price Sheet Advance. It's possible that Canadian market cars lack these normal codes or use Z31 instead.

 It might have something to do with a credit back to the dealership via some sort of dealer promotion or other incentive. There's a correlation in what I've seen, that these cars above were all built around September, so perhaps there was a special promotion these years for dealers to get a small discount of around $1000 if they accepted cars this time of year... or something along those lines. The customers wouldn't have necessarily seen the discount, in fact, they were unlikely to see the discount passed on to them, but the dealership purchasing the car would have been given an incentive to order the car. More research needed. 

R7R

Control Sales Item. This code clearly has an inconsistent definition.

For 1996, this appeared on 8,094 1996 RS coupes and 905 1996 RS convertibles. It means Domestic Delivery for Y3F (RS). Also known as Camaro Rally Sport Identifier. The car will have L36 V6 engine if it is an RS. 

For 1994, there were 87,718 Camaro coupes and 7,169 Camaro convertibles with this code. Take note--that means this code appears on ~80% or more of '94 Camaros based on those numbers. I've seen this code on a '94 LT1 Z28 convertible, so it certainly was not an RS, nor a V6 Camaro. I've also seen it on a '94 L32 V6 Camaro coupe. 

In 1995, there were 10,087 Camaro coupes with this code. I don't know the numbers for convertibles. I've seen it on a '95 L32 V6 Camaro coupe as well as a '95 LT1 Z28 Camaro coupe. 

R7T

1996-1997 SS package by SLP Engineering. It was only available on Z28s.

WU8 does appear on some of the '96-'97 SSes. R7T typically shows up on '96-'97 SSes while Canadian '96-'97 SSes typically have WU8. Many cars have both codes. 

R7T may have been used to specify that the '96-'97 SS was built for Domestic Delivery to the US. I checked a '96 Canadian SS, and it did not have R7T, so this could be a valid point of difference, however, more than 1 car needs to be looked at.

R7V

Control Sales Item No. 46. This code is seen on around 26 1995 Firehawks for some reason. I don't know what it means. It has a generic definition of "option identifier" in some things I've seen.

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. I've also seen this code on one of the 2002 sebring silver Indy 500 convertible Z28 festival cars (no, not one of the Z7D SSes, one of the Z28s, though the SSes might have it too...).

R8S

This code will need more research, but signifies "Multiple Order Numbers." I don't know what that means yet. It was a "no additional charge" option.

R8T

Control Sales Item No. 69. This code signifies "Preliminary Invoice (Refer to Vehicle Price Schedule)" in the '97 ordering guide. The vehicle price schedule was the official pricing documentation of Chevrolet Motor Division and was supposed to be used when discussing vehicle prices with potential buyers. In 1993 it meant "Priced Order Acknowledgement." It was a "no additional charge" option.

I would guess R8T has something to do with telling GM that a buyer was told prices based on the preliminary invoice when placing the order for the car.

R9H

Control Sales Item No. 83 I think.

I don't know what this means yet, but it was on the '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX). 

R9W

Control Sales Item No. 97. Rear window defogger not desired. There are no lines on this glass. It was first available as an option in 1993, but it was definitely a new option for '95 B4C cars based on the '95 B4C brochure. It may (or may not) be safe to assume that '93 and '94 B4C cars cannot have R9W.

R9Z

Control Sales Item No. 100. POMS Auto Sequence, Ste Therese, GM Of Canada Plant Code.

May mean Production Order Management System or could mean Product Order Management & Scheduling (a system that is used to determine whether a vehicle is buildable based on available engineering specifications). I have no idea which one is correct.

It probably means that it was a customer ordered vehicle. On 2001-2002 Camaros with R9Z, you'll usually (always?) see SLL on the car too (which means sold orders). On 1999 Camaros, you'll just see R9Z. I saw R9Z on a '95 Z28 and it did not have SLL. Eventually I'll know the exact pattern and cutoff, but for now, this is a work in progress.

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. I've also seen it on two rather normal '95 Z28s.

SLL

Sales Processing - Sold Orders. This means the customer special ordered this car. This code was used from 2001-2002 and you'll usually (always?) see R9Z on these cars that have SLL. 

SLM

Sales Processing - Stock Orders. This means the car was a Dealer Stock order. This code was definitely used in 2002 but I don't know the complete year range this was used yet.

STE

Plant Code for Ste. Therese where all of the 4th gen Camaros and Firebirds were built.

T2H

Extra Ornamentation for Export models. (shows up in '97 ordering guide)... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T2J

It has something to do with the center (floor) console, possibly specific to export models... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T37

It might have something to do with deluxe fog lights used with "international WJ9" whatever that means (and the car I saw T37 on did not have WJ9)... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T39

This might have something to do with auxiliary turn signal lamps on exported Camaros... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T43

A Firebird code. Uplevel Rear Spoiler. It was for 93-02 Trans Ams and 96-97 LT1 Firehawks. 

T61

Daytime running lights. This RPO code might be specific to 1995 and 1996, because 1997 - 2002 cars should have T82. I witnessed this RPO code on a '96 Canadian SS and '95 Canadian 3.8L V6 Camaro coupe.

T62

Daytime running light delete... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T65

Daytime running light for Export... I need to research this one more. I saw it on a 1998 Camaro Z28 that was exported to Norway. 

T78

I saw this on '02 V6 Firebird 2G2FS22K622151008 and haven't decoded it yet. On a Camaro, I saw it decoded (possibly) to headlamp control delete... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium.  It had a headlamp switch to the left of the steering wheel, so I don't understand this code right now, but it also had T62, so daytime running lights were deleted. I also saw this code on a 1998 Camaro Z28 that was exported to Norway, and it had T65 daytime running lights for export. 

T79

This might be Rear Fog Lamps (for some of the exported cars)... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium.

T82

Twilight Sentinel Headlamps (this is automatic daytime running lights, which became available in 1997).

T84

This might decode to Right Hand Rule of the Road Headlamps... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T89

This might decode to Tail and Stop Lamps for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T90

This might decode to Signaling and Marker Lamps for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

T96

Fog lamps (for '93 this required K34 cruise control and again in '97 it is mentioned that K34 is required).

TR7

It has something to do with the center (floor) console OR Automatic Headlamp Contol Leveling System... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium as well as some other cars. 

TS9

This was seen on a 2002 35th Anniversary Edition SS. I need to research this one more, but it supposedly means high level stop lamp delete. Not sure what/why. More research needed. It shows up on a lot of the 2001-2002 SSes. Perhaps the base model/Z28 spoiler was put on the SS for transportation, but they stopped including the third brake lamp in it...? Not sure yet.

U1A

To my knowledge, this was a radio code for a '90-'92 Camaro with CD player. If it shows up on a '93 Camaro, I'll be shocked. Show me if you have this code and what radio your car has. If your car has U1A, I bet you have U1T as well, which is the code you should have. This code supposedly shows up only on some/many of the B5A Indy 500 Pace Cars.

U19

Speedometer in kilometers per hour. Canadian cars and others had this.

U1S

12 disc CD changer (requires UL0 Radio from 1998-2001 and in 2002 requires U27 Radio--there might be other restrictions for other years, but I don't have those references yet. Looking at a Canadian '97 30th Anniversary Edition Z28 coupe that has U1S, it does happen to have UL0 and UZ7)

U1T

1993 - 1995: Delco/Bose music system: electronically tuned AM/FM stereo radio with seek-scan, random, HPS, balance control, compact disc CD player, digital clock, and Delco Loc II (from 1993 - 1994 it required C60 air conditioning and U82 speakers, in 1995-1996 it required C60 air conditioning and U65 speakers)

U27

Introduced in 2002 (at least according to the 2002 B4C brochure) Monsoon 500 Watt Peak Premium Sound System, electronically tuned AM/FM Stereo Radio with seek/scan, digital clock, cassette tape player, Dolby noise reduction, automatic tone control, speed compensated volume, 8 speakers and amplifier, music search, and Theft Lock. 

U65

Bose speakers, required with UU8 or U1T (1995-1996)

U59

This likely has something to do with the radio or speakers in a Camaro Convertible.  I saw this code on a manual 2001 V6 Camaro Convertible exported to Belgium. More research is needed.

U73

Fixed antenna for the radio, it was not a power antenna that went up and down. This was standard on most (nearly all) Camaros.

U75

Power antenna. I know these were common on Trans Ams, but I think this might have only been available for export Camaros. I'll need to do some more research. It shows up in the '97 Camaro ordering guide. 

U82

Bose speakers, required with UU8 or U1T (1993 - 1994). This was a 3-speaker system including dual door mounted, rear quarter-left subwoofer. The subwoofer was only on the driver's side.

UA6

Theft deterrent alarm system. Definitely seen on many, many, many '96-'02 Camaros. Might be on some '95s, but not sure yet.

UB3

Instrument Cluster (oil, coolant temperature, voltmeter, tachometer, trip odometer). 

Seen on a '97 V6 Camaro, a '94 Puerto Rican export Z28 that had a 150 mph speedometer (not sure if it was original to the car though...), a Canadian '97 30th Anniversary Edition Z28 coupe, a '95 3.8L V6 Canadian coupe, a 2002 35th Anniversary Edition SS, and a 1999 V6 Camaro that was exported to Belgium. More research is needed. 

Some definitions imply that it is an instrument cluster with tachometer in general, and all '93-'02 Camaros had a tachometer. 

Specifically: Instrument Cluster (Oil, Coolant Temperature, Voltmeter, Tachometer, Trip Odometer) Gauges.

UC2

This might have something to do with a positive bias speedometer to be installed that has KPH and MPH, with a Kilometer odometer... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

UD4

Vehicle speed alarm (supposedly 120 kph... will need more research)

UK1

Japanese radio frequencies. A pretty good way of identifying a Japanese exported Camaro.

UK2

This might have something to do with a directional signal lever for exported cars... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium as well as a '99 Z28 exported to Belgium. 

UK3

First available in 2000, this is leather wrapped steering wheel with redundant radio controls (requiring UL0 or UN0 radio), and it also included leather wrapped transmission shifter and parking brake release handle.

UL0

Radio Delco/Audyssey (officially labeled Monsoon in the year 2000) 200-watt music system, electronically tuned AM/FM Stereo Radio with seek/scan, digital clock, cassette tape player, Dolby noise reduction, music search, and Theft Lock (first available in 1997). In the 1998 description, it mentions automatic tone control, speed compensated volume, 8 speakers and amplifier. In 2001, (unless the 2001 B4C brochure is incorrect) this RPO remained the same, but the music system was upgraded to Monsoon 500 Watt Peak Premium Sound System.

UL2

This might have something to do with European Radio Frequencies... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

UL8

This might have something to do with an AM/FM stereo with tape deck for an exported car... I need to research this one more... I'm doubtful of that being the correct definition. I saw it on a 1998 Camaro Z28 that was exported to Norway.  The car also had UW3 and UZ7.

UM6

AM/FM Electronically Tuned Radio with CD player required with UQ0 speakers.

UN6

AM/FM Electronically Tuned Radio with Cassette player required with UQ0 speakers. This radio was the standard radio and featured dual directional seek and scan, auto reverse, music search, clock.

UN0

Radio Delco/Audyssey (officially labeled Monsoon in the year 2000) 200-watt music system, electronically tuned AM/FM Stereo Radio with seek/scan, digital clock, compact disc CD player, and speed compensated volume (first available in 1997). In the 1998 description, it mentions automatic tone control, Theft Lock, 8 speakers and amplifier. In 2001, (unless the 2001 B4C brochure is incorrect) this RPO remained the same, but the music system was upgraded to Monsoon 500 Watt Peak Premium Sound System.

UQ0

Standard base-model speakers, required with UN6 radio (and later with UM6 CD radio). It was a 4-speaker system with dual door mounted, dual standard range quarter high sensitivity 6" round speakers.

UU8

1993 - 1996: Delco/Bose music system: electronically tuned AM/FM stereo radio with seek-scan, stereo cassette tape, auto reverse, music search, HPS, Auto Dolby B, and digital clock (from 1993 - 1994 it required C60 air conditioning and U82 speakers, in 1995-1996 it required C60 air conditioning and U65 speakers)

UW3

This might have something to do with a European Export radio with AM/FM stereo, seek/scan, auto rev music search cassette, data system, clock, ETR... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium.  

UZ7

1997 - 2002: Monsoon Premium Sound System With 8 Speakers And Auxiliary Amplifier (Base System Z28 & Uplevel on Base coupe).

What's interesting is that the '97 ordering guide does not show this RPO code in it.

V12

Power steering cooler. This was introduced in '98 and I think all '98-'02 Z28s and SSes had it, but I'm not 100% positive it was all of them.

V2G

I've seen this defined three different ways, and I don't yet know which one is correct, or the most correct. "Credit - Full Fuel Fill" or "Retail Amenity Delete" or "Delete - Full Fuel Fill"

Seen on a few B4C cars. I would assume it means that the car would not be filled completely with gasoline for whatever reason.

V73

Vehicle Statement - US/Canada. I believe this means that it was certified for use in the US and Canada.

V76

Front tow hook for Export. Witnessed on a '94 Puerto Rican export Z28 and a 1999 V6 Camaro that was exported to Belgium. 

V78

This might mean Vehicle Statement Delete for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VA5

This might mean English Language Label... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VB1

This was some sort of label signifying that the car was shipped to Japan. There should be a label somewhere on the car supposedly that is associated with this. It's associated with at least 1993 models. Note: Japanese exports, at least for 1993 if not all '93-'02s, all had the U75 power antenna.

VC4

Fuel economy label price for Puerto Rico and Virgin Islands.

VC5

This might mean Shipping Label, Except US, US Possessions, or Japan... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VD1

This might mean European Provision Options for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VE2

Not sure what this means, but "protector source applied". This has been seen on mostly 2002 35th Anniversary Edition SS Camaros, but also supposedly seen on a 1997 SS and a 1999 SS as well. Weird. I also saw it on a 1999 V6 Camaro that was exported to Belgium. 

VE3

This might be related to some sort of label in the engine compartment about a battery disposal label pertaining to the European Economic Commission (ECE Regulation--an environmental protection regulation). I saw it on a 1998 Camaro Z28 that was exported to Norway. 

VG1

Water-based clear underhood compound for protecting and preventing corrosion. This was for some export Camaros. Witnessed on a '94 Puerto Rican export Z28 that no longer had the factory hood unfortunately. It was also witnessed on a 1999 V6 Camaro that was exported to Belgium that had the factory hood. From what little of the underside of the hood I can see, I don't see anything unique.

VG4

Water-based black undervehicle compound for protecting and preventing corrosion. This was for some export Camaros. Witnessed on a '94 Puerto Rican export Z28 and a 1999 V6 Camaro that was exported to Belgium. 

VG8

This might mean Notice to Buyer Label. I need to research it.

I don't know what this means yet, but it was on the '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX). Worth mentioning, this car has VS7 and WD2.

VG9

Exterior body protector wax (or guard...?) for some export Camaros. Witnessed on a '94 Puerto Rican export Z28 and a 1999 V6 Camaro that was exported to Belgium. This code might mean slightly different things over the years. It might have been a wax for earlier cars, and replaced with some sort of foam or plastic or something else for later years. I need to research this more or see what exported Camaros looked like when delivered in Europe and other places.

VH3

5 mph impact bumper info label for Hawaii. All of the '93-'02 Camaros had 5 mph bumpers front and rear, so this RPO must have been created to be in compliance with Hawaii's rules (I assume).

I saw this on a '94 Trans Am, but I assume it's possible to find on Camaros as well.

VH5

This might have something to do with a Vehicle Identification Plate on an Export. ... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VJ4

This might mean Child Seat Location Label for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium.

It might be related to this sticker appearing on cars with this RPO code.

VK3

Front license plate bracket. 

This would be in the trunk of the car when delivered to the dealership and installed by the dealer. The dealer would have to drill holes in your bumper.

VL4

This might be related to Front License Plate Mounting Package for EEC (European Economic Community? European Export Car?)... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium.

The EEC brought together 6 countries (Belgium, Germany, France, Italy, Luxembourg and the Netherlands) to work towards integration and economic growth, through trade. I'm not sure if that's what EEC stands for in this code's description... it might just mean European Export Car.

VL5

This might be related to Rear License Plate Mounting Package for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VL7

This is in regard to standard impact bumpers (5 mph) front and rear for New York. This RPO likely existed due to a legal reason back in the day (some sort of compliance) because all '93-'02 Camaros had energy-absorbing front and rear 5 mph bumpers. It must have needed to be specifically called out to New York for some reason.

 You'll see this code on cars that were sold from dealerships in New York. You're very likely to see this on cars that also have NG1 (Northeast States Emissions). Not all NG1 cars have VL7, but I believe all VL7 cars will likely have NG1.

VM3

Information label regarding standard impact 5 mph front and rear bumpers. All 1993-2002 Camaros had 5 mph front and rear bumpers.

The NHTSA is well known for their 1970s rubber bumper rules, but in 1982 they amended their 5 mph rules to be just 2.5 mph for 1983 models, and that rule lasted for many years. I'm not sure when/if it has technically changed. But the 4th gen Camaro featured 5 mph front and rear bumpers for each year, so it was something Chevy would brag about.

VP6

This might mean Noise Level Control... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium as well as a 1998 Camaro Z28 exported to Norway. 

VQ1

Fleet ordering & assistance program with quarterly holdback (holdback applies).

It might appear on most/all cars with R6D, but I have no way of checking that. This is also associated with many B4C.

Based on a 2016 GM document (so it was probably a little different 20 years earlier) about GM Fleet and Commercial orders... If a dealer orders VQ1, 3% holdback will be charged and the holdback repayment will be Included in the dealers normal holdback payment at the end of the next quarter (even if the dealer has chosen monthly repayment for their retail vehicles). 

VQ2

Fleet ordering & assistance program without holdback (holdback not applicable).

No clue what that actually means, but all B4C have it, as well as (some? all?) Camaro RSes, as well as (some? all?) cars with C1U.

Based on a 2016 GM document (so it was probably a little different 20 years earlier) about GM Fleet and Commercial orders... If a dealer orders VQ2, no holdback will be charged and no repayment will be made.

VQ3

Fleet ordering & assistance program with monthly holdback (holdback returned monthly).

I haven't seen this on a car yet, but I bet it exists. It is probably seen on some B4C cars.

Based on a 2016 GM document (so it was probably a little different 20 years earlier) about GM Fleet and Commercial orders... If a dealer orders VQ3, 3% holdback will be charged and the holdback repayment will be Included in the dealers next monthly holdback payment. 

VR6

Hook Tie Down
This shows up in the '97 ordering guide. I assume it's for the 2 hooks mounted behind the rear seat. Witnessed on a '94 Puerto Rican export Z28, but I don't see anything visually unusual, there aren't hooks on the hump behind the rear seat on this car.

VR7

This might mean Second RR (Right Rear?) Tow Hook for Export... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

VS7

Non-Saleable Vehicle (often WD2). The '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX) features this VS7 code. 

W54

I don't know what this means yet, but it was on the '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX). 

W55

I saw this on '02 V6 Firebird 2G2FS22K622151008 and haven't decoded it yet since I haven't seen it on a Camaro yet.

W66

I don't know what this means yet, but it was on the '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX). 

W68

I saw this on '02 V6 Firebird 2G2FS22K622151008 and haven't decoded it yet since I haven't seen it on a Camaro yet.

WD0

Start of Platform Containment Vehicle. 

I know of several cars with this code...

3 of these cars were '97 white Z4C Z28 convertibles with automatic transmissions that possibly had something to do with the Brickyard 400 festival cars; in fact, they might (or might not) have been given Brickyard 400 decals as well. Their VINs were 2G1FP32P6V2100071, 2G1FP32P5V2100076, and  2G1FP32P7V2100077. They were all built on May 2, 1996 (one day before the very last Brickyard 400 cars were built) and these three cars have completely identical RPO codes, and were thus completely identical cars. The owner of 00076 contacted me and is named Henry Wybenga, and he shared the full VIN of his car, which allowed me to decode it, and also gave me a hint at what the VINs for 00071 and 00077 would be. After some trial and error, I figured them out. Henry's car (like the other two) does indeed have WD0 as well as WD1, and it is a Z4C 30th Anniversary Edition Z28 convertible with an automatic transmission. I compared his cars' RPO codes to a '97 Brickyard 400 30th Anniversary Edition Z28 convertible that I randomly selected (VIN 2G1FP32P2V2100066) and his car has exactly the same RPO codes as it, except he also has WD0. Both Henry's WD0 car and this randomly selected Brickyard 400 car were built on 5/2/96 (00071 and 00077 were built the same day as well). 

Another car I've found with WD0 is a 1998 Camaro Z28 exported to Norway.

WD1

Pilot Vehicle, sometimes VS7. 

All 50 1997 Brickyard 400 30th Anniversary Edition Z28 convertibles had WD1. In order to be a '97 30th Anniversary Edition Brickyard 400 Camaro Z28 convertible, each of the 50 cars had these codes:  10C, 10T, 10U, 1SM, AG1, AR9, AU0, B35, FE9, GU5, LT1, MX0, NW9, QFZ, UN0, WD1, Z4C. There were three cars with all of these codes plus WD0, however, I have not determined if they were used at the race, that they definitely had Brickyard 400 decals on them, or why they are not included in the list of 50 cars. These cars have VINs ending in 00071, 00076, and 00077. It's possible that there were technically 53 Brickyard 400 cars for this year, but I have not confirmed that.

Relevant to the Brickyard cars, it is notable that there isn't a 00064 on the list at all. I determined the car was 2G1FP32K3V2100064. It was a '97 white convertible with light gray leather, black top, manual transmission, V6 engine, Y87 (performance handling package available for V6 cars), N96 (Z28 wheels), produced on the same day as many of the Brickyard 400 cars (May 2, 1996). It also has WD1... so it was a pilot vehicle of some kind. I'm curious if there was a conspicuous white V6 Camaro convertible with gray leather at the Brickyard race or not. Email me if you have info!

Update: I found a 1998 Camaro Z28 exported to Norway that also has this code.

WD2

Prototype.

The '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX) features this WD2 code. 

WS9

I don't know what this means yet, but it was on the '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX). 

WU6

For Firebirds... In 1999, this became the designation for the Firehawk package. It could be applied to any Formula or Trans Am and required QLC. It could not be ordered with WS6 (Ram Air Package), P05 (Chrome-plated Aluminum Wheels), 1LE (Performance Package), or QFK (17" Goodyear Eagle F1 tires).

WU8

In 1998, this became the specific designation for the SS package. Why the change from R7T? To keep this explanation simple, it was because some SS equipment was installed at the factory in Ste. Therese. The cars were still shipped to SLP in LaSalle Quebec for installation of the SS hood, spoiler, and optional SLP components, however. By doing some of the SS conversion "in house", the price of getting an SS was a little bit lower.

WU8 does appear on many of the '96-'97 SSes, but not all. R7T typically shows up on '96-'97 SSes while Canadian '96-'97 SSes typically have WU8. Many cars have both codes. You will not find WU8 on a Z4C 30th Anniversary Edition SS, because you will find WU9 instead.

WU9

Specific to 1997, Sales Package Anniversary Z28 SS. This code meant this car was to be built as a white and orange striped anniversary car and then converted to an SS by SLP. Note: 167 30th Anniversary Edition Camaro SSes lack R7T but have WU9. WU9 essentially forced R7T onto the car even if it isn't on the RPO code sticker. It's thought that if the dealership ordering the car didn't check-mark the box for R7T, WU9 would suffice--as it is basically saying "build this as a 30th Anniversary SS whether it has the normally required R7T or not."

WX7

This might mean Separate Fusing Wiring Provisions... I need to research this one more. I saw it on a 1999 V6 Camaro that was exported to Belgium. 

Y2Y

Introduced in the year 2000, this code means SLP 2nd sticker content. In other words, there was a sticker (placed on the edge of the passenger door) that stated what additional SLP options a Camaro SS was to have. An SS does not have to have this RPO code. SSes that have it definitely had at least 1 additional SLP option installed on the car by SLP even if it was just as simple as floormats.

Y3B

The 2001-2002 Camaro RS by SLP. This was the Rally Sport package for V6 coupes and convertibles. It included dual black or silver Heritage stripes, a unique grill with Chevrolet “bow tie” logo, RS interior plaque (that was to be installed by owners or dealers in place of the plastic one all Camaros came with) and exterior RS badging, dual outlet Z28-style exhaust (boosting the 3800 V6 to 205hp). Read my page about these unique cars for more details.

Y3F

1996 to 1997 it is RS Sales Package. 1998 to 2002 it is Sport Appearance Package. This was an option that added ground effects and a rear spoiler extension to the car. For 1996 and 1997, this was the designation for the Camaro RS (which featured these items) and was a V6-only model. For 1998 through 2002, it was the Sport Appearance Package, and could be applied to V6 Camaros as well as Z28s. On V6 cars, Y3F required 16 inch aluminum wheels (in other words, you couldn't order a V6 Camaro with steel wheels and hubcaps if you got Y3F or an RS).

Y87

Performance Handling Package for V6 Camaros. It included a limited slip axle, 4-wheel disc brakes, dual outlet exhaust, and sport steering ratio. It required QCB tires and N96 wheels and automatic Camaros with Y87 received a 3.42 axle ratio (GU6 with G80 limited slip differential).

YA7

California emission test. This was a required test for (all?) Camaros with California emission requirements. Most decoders mention California Assembly Line, but unless Ste. Therese had a separate run time or something specific to California cars, that statement is a bit odd. All 4th gens were produced by Ste. Therese in Canada.

I saw this on a '94 Z28 convertible with YF5 emissions. It definitely appears on many California Z28s and SSes. It's also on the '98 car used for creating the 2003 Trans Am 421 SD concept car (VIN 2G2FV22G5W20016EX) along with YF5. 

YF5

California emission requirements (at least for 1994, an $86 dealer invoice (dealer price $83) and $100 MIGHT be what's on the window sticker). This code was definitely present in 1998 as well. I'm unclear on some things about this code, and it needs more research. In 2000, this was available as an option for B4C cars and it was simply called California Emissions. In 1993, it was simply called California Emissions as well. I've seen it labeled "50-state Low Emission Vehicle" by some decoders but I think that's a bit odd.

All '95 L36 V6 engine Camaros were supposed to have YF5 emissions if they had an automatic transmission, so likely close to 100% (... I've definitely seen 1 Canadian '95 L36 coupe with FE9 instead of YF5).

YK6

For 1993: Pace Car Identification (specific to the '93 B5A Indianapolis Pace Car special editions).

For 1994 (and maybe other years): Special Equipment Identification (B4C only)

Z28

Special Performance Package. On a 4th gen Camaro, this guarantees the car had a V8 engine regardless of the year. There were not any V6 cars with the Z28 code.

The history of the name Z28 is best explained here. In short, the RPO code was Z28, so the '67 Camaro Z-28 was called that. The car got its name from the actual option code. Ironically, for 1967, Z27 was the RPO code for the early Camaro Super Sport package and Z28 simply followed it sequentially. The Rally Sport was Z22 back then as well. It seems as though the 283 engine (which was replaced by the 302) was coincidental in that it had a "28" in it. "Z27" was not the RPO code for a SS because it had anything to do with "27".

The "Z" has nothing to do with Zora Arkus-Duntov, the Corvette engineer. 

The letter doesn’t mean or stand for anything specific, and it has been used for hundreds of options over the decades, both big and small. A Z-code has, however, been used for many of Chevy’s iconic performance packages and high-performance engines over the years. Why? Most likely just because the 1960s Z11 Impalas, Z06 Corvettes, Z16 Chevelles, and Z28 Camaros made the "Z" sound cool. It became a marketing tool. Eventually there was the ZL1 Camaro and Corvette, ZR1 Corvette, ZR2 Corvette, and even more Z's later--IROC-Z Camaro, Z24 Cavalier, Z26 Beretta, and Z34 Lumina. Most of the '90s ones certainly were living off the "coolness" of the Z28.

But as you can see below, many of the Z-codes are not necessarily performance-oriented or special. Look at Z31 specifically. 

Z28 was just a sequential RPO code with no particular greater meaning. "Camaro Z28" rolled off the tongue and sounded cool, so instead of coming up with a more creative name, Chevy branded the special performance package the Z/28 and it became the name as a result. It was not meant to stand for something or be the abbreviation for anything. The claim that it has anything to do with (for example) Z-rated tires, 2-doors, 8-cylinders, is purely creative writing/fan-fiction. 

Z31

Identification: Price Sheet Advance, also called a Preliminary Invoice.

I don't have a full understanding of what this means.

This RPO code was seen on the very last 2002 Firebird built--a car full of very unusual RPO codes. The very last 2002 Camaro built did not feature many unusual RPO codes and did not have this one. 

I've also seen Z31 on two '96 Canadian SSes, a '95 3.8L V6 Canadian coupe, and several Canadian Z28s. There may be a correlation/relationship with Canadian Camaros and Firebirds and this particular code. Worth mentioning, in the Canadian cars I've looked at, they did not have any of the possible codes for dealer stock vs. customer ordered, so this Z31 code may have some sort of significance toward that for Canadian cars (...or not... this is just a theory). More research is needed.

Z49

A 4th gen made for the Canadian market. Mandatory Canadian base equipment modifications (Canada) which included a speedometer in kph. I'd like to call this "export Camaros for Canada", but considering 4th gens were made in Canada, I have trouble with the idea of calling them Canadian Export models.

At least for 1994, all Z49 cars included AN4 and K05 (engine block heater).

Z4C

Anniversary Edition Appearance Package: 1997 30th Anniversary Edition Z28 or SS and 2002 35th Anniversary Edition SS

All '97 30th Anniversary Edition Z4C cars required the car be ordered with AG1 (6-way power driver seat), coupes had to have 1SJ (preferred equipment group 2), and convertibles had to have 1SM (preferred equipment group 2). These cars had to have QFZ or QLC tires. The RPO code WU9 (Sales Package Anniversary Z28 SS) was sometimes used on the 30th Anniversary Edition SSes to denote them as SSes WITHOUT the normally required R7T. 167 30th Anniversary Camaro SSes lack R7T but have WU9. None of the '97 Z4C cars were RPO EXP exports.

ZV1

Manufacturer's Statement (or Certificate) of Origin. I've seen this on a 2002 35th Anniversary Edition SS (that was SLM - dealer ordered stock) as well as a 2002 silver SS (that was SLL - sold order, customer ordered vehicle). I did not see any other unusual codes on these cars, so I don't know why this was used, why it appears very rarely, etc. 

Other codes on your sticker

You'll see other codes on your sticker, one code above the RPO codes and several below them. To be honest, these codes are not particularly interesting, but I wanted to at least mention them. Example:

1FP87 BC/CC U 8774 192

1FP87 is the engineering model number. 1=Chevrolet, F=F-body, P=Camaro, 87=coupe

BC/CC = Base Coat/Clear Coat paint

U 8774 = Upper exterior paint color (in this case, red)

192 = a duplicate listing of what color your interior should be (this code will appear in your RPO code list as well)

Other resources for RPO code info

Part of the reason I made my page is because many other resources are generic to all GM models and/or Camaros regardless of year, and this results in inaccuracy. Moreover, some of these resources disagree with each other on some codes, because they are generic to many different GM cars for decades. I do look at these when I am researching and writing content, however, because I have to make sure I prevent making mistakes. Here are some of the sites I look at:
