Weight and appearance

Length and width

1. Overall width shall not exceed 2 3/4 inches at the furthest horizontal protrusion, whether it is the body of the car, or the wheels. The area where the axels are inserted should be approximately 1 3/4 inches wide to ensure that the wheels will fit over the guide strip on the track.

3. The wheelbase (distance between the centers of the front and rear axles) must measure between 4 3/8 and 4 5/8 inches. Basically the same distance already cut into the block
4. Height of the car shall not exceed 3 inches.
5. The entire car must stage behind the starting pin.

Wheels and Axles

1. In order to qualify for racing, only BSA official wheels and axels may be used. Do not use wheels and/or axels available in hobby stores or online. These may be more highly machined than the “Official Grand Prix Pinewood Derby Kit” and represent an unfair advantage. The use of any other wheels and/or axels will result in the disqualification of the vehicle from competition.
2. No alteration, narrowing, lathe cutting, or re-shaping of wheels (inside or outside) is allowed. Light sanding of the wheel treads to remove irregularities is permissible.
3. No alteration, narrowing, lathe cutting or reshaping of wheel hubs is permitted. Light sanding of the hub face to smooth the surface is permissible.

5. Wheel bearings, spacers, and washers are prohibited.
6. The car shall not ride upon any type of springs.
7. All cars must have four wheels. Three of the wheels must be touching the track surface at all times.
8. The car must be free-wheeling with no starting or launching devices.
9. Only dry lubricants such as graphite or powdered Teflon "white lube" will be allowed for lubricating the wheels.

Inspections and Disputes

1. Each car must pass inspection of the Official Inspection Team before it may compete. The Official Inspection Team has the right to disqualify those cars which do not meet these rules. Car owners will be informed of the violations and given an opportunity to modify the car to meet these rules.
2. Any participant (including parent of the participant) has the right of appeal to the Rules Committee for an interpretation of these rules. The Rules Committee, by majority vote, will be the final judge of these rules.
