Classifying Your Car

Below is a list of items considered to be MINOR, MEDIUM and MAJOR Modifications.  This list is subject to change.  Final decisions on all classing will be at the discretion of the show committee.  Every effort is made to keep these classing guidelines in line with the standards at the National Fiero Shows per Fred Bartlemeyer.  As a general rule of thumb, most shows will contain the following criteria for classes:

All classes -  Unlimited maintenance changes (see below)
Factory Stock - for cars that are as original as possible.  Same qualifications as stock; however, points will be deducted for non-maintenance changes (i.e. adding an aftermarket radio) and maintenance changes that are not OEM (i.e. polyurethane instead of rubber bushings).  Paint may also be taken into consideration, as original paint is preferred over repainted cars. 
Stock - 3 or fewer minor changes. No medium or major changes
Custom - Unlimited minor changes or medium changes. No major changes
Modified - Unlimited medium and minor changes.  Anything that contains a major change.
