Please read these Rules and Instructions before building your car.

The Pinewood Derby is open to all Cub Scouts. Cars should be built by the Cub Scouts with some adult guidance. Any technical assistance should be fully explained to the Cub Scout so that he can use that knowledge on future projects.

 

  Maximum width - 2-3/4"

  Maximum Length - 7"

  Maximum Weight - Not over 5 Ounces

  Minimum width between wheels - 1-3/4

  Minimum bottom clearance underneath the body (so it does not rub on the track guide) - 3/8"

  All 4 wheels much touch track at all times

  Use only Official BSA Pinewood Derby Kit wood, wheels, and nails.

   Wheels may only be lightly sanded to smooth out molding imperfections in the tread area. Beveling, tapering, thin sanding, wafering, or lathe turning of the wheels is prohibited. The decorative dots on the wheel treads may not be removed. (Lathing of wheels can make cars much faster.)

   Wheel bearings, washers, and bushings are prohibited. The car shall not ride on springs.

   Motors, engines, or other propulsion may not be used.

   The Minimum Front Nose Width shall be at least 0.5” and parallel with the front axle to operate properly on the track. Cars must be no more than 3.5" high to fit under the finish gate.

   Axles and wheels may be pre-lubricated using dry powdered lubricant only.

   Details, such as steering wheel, driver, fins and scoops are permissible as long as these details do not exceed the maximum length, width and weight specifications.

   All cars are to be inspected and stored safely prior to the race.

   Each car must pass inspection by the official inspection committee before it may compete. If, at registration, a car does not pass inspection, the owner will be informed of the reason for failure, and will be given time within the official weigh-in time period to make the adjustment.

After final approval, cars will not be placed in the “pit area”.  There will be no further alterations or additional lubrication can be applied after car is approved for racing. 

If during the race the car is damaged, the scout and parent(s) can fix the car but must have it ready by the scout’s next race.
