Body, Wheels, Axels

Body, Wheels, Axels

1. Axles and wheels shall be only as provided in the Official Grand Prix Pinewood Derby Kit.

2. You MUST use the block of wood provided. Purchasing pre-made bodies is NOT ALLOWED. 

3. Wheels may be lightly sanded to smooth out molding imperfections on the tread area. This light sanding is the only modification allowed. Beveling, tapering, thin sanding, wafering or lathe turning of the wheels is prohibited. 

4. Axles may not be altered in any way except for polishing.

5. Wheel bearings, washers, bushings, and hub caps are prohibited.

6. The car shall not ride on any type of springs.

7. The car must be free-wheeling, with no starting device or other type of propulsion.   


1. Use graphite only. Oil damages the paint and collects dust. I'm told that the graphite works better than the new white Teflon.

2. Break in the wheels by spinning them with lots of graphite. 

3. Right before check-in, fill the wheels wells with graphite and cover  with stickers like a hub cap. You can paint the 1 inch stickers in a  contrasting color. It looks great! 

4. Put a small drop of white glue where the axle goes into the car body and put powdered graphite on it there. That causes less friction if the wheel should rub against the car body.

5. Other than the good polishing of the axles, dump the axles and wheels in a ziplock bag with some graphite and shake them for a few days prior to the race. That way the wheel and the axles are as slick as can be.
