MATCHING MOLD NUMBER WHEEL SETS ARE STRICTLY PROHIBITED. NO MORE THAN 2 WHEELS MAY HAVE THE SAME MOLD NUMBER. AT LEAST 3 DIFFERENT MOLD NUMBERS MUST BE USED.

14. CONSTRUCTION: No complete cars purchased from outside sources shall be entered. Cars are to be constructed expressly for this year's race by the participant and his adult leader. Pre‐shaped body kits (like those available at Michael's) may be used so long as the wheels and axles used are from the official BSA kit. Please note that many of the pre‐shaped body kits come with wheels and axles do not conform to the rules.
