Pack 6 Pinewood Derby Rules

  • The car must have been made during the current year (year in which derby is being held) and must be made by the scout - Cannot use previous years cars, or purchased cars
  • 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 re-inspected unless the car is damaged in handling or in a race.

Car Specifications:

  • Width: - 2-3/4"; Length - 7"; Weight - Not over 5 Ounces; Width between wheels - 1-3/4" [The dimensions of the wood block]
    • Underside clearance of at least 3/8 (0.375) inches and inside wheel to wheel clearance of at least 1 3/4 (1.75) inches is recommended, so that the car will run on the racetrack. Adequate clearance is the responsibility of the race car builder.
    • Details, such as steering wheel and driver are permissible as long as these details do not exceed the maximum length, width and weight specifications.
    • The car must be free-wheeling, with no starting devices.
    • Gravity Powered: The race car may not be constructed or treated in such a way that the track's starting mechanism imparts momentum to the car. (For instance, this provision disqualifies cars with sticky substances on the front of the car and protrusions which may catch on the starting pin.). This also precludes propulsion systems (compressed gas, motors, etc).
    • The car shall not ride on springs.
    • Staging: The entire car must stage behind the starting pin.​
  • Wheels:
    • Only official Cub Scout Grand Prix Pinewood Derby wheels and axles are permitted. [only the wheels and axles from our kits]
    • Wheel bearings, washers, and bushings are prohibited.
    • Wheel treatment (hub and tread smoothing and polishing) may not result in substantial removal of mass nor in reducing the tread (track contact) width from the original kit wheels. Wheel tread surface must be cylindrical. The words "Official B.S.A. Made in U.S.A." and other lettering on the wheels shall remain intact and clearly visible to the inspector. Some of the original "tread marks" on the wheel face must be intact, i.e. apparent to the inspector.
  • Only dry lubricant is permitted.  [We will be providing graphite to all racers, wax is considered to be a wet lubricant]

Note: there is no requirement that all wheels must touch the track.
