Pinewood Derby

Race Information

  • In case of illness or a valid conflict, an absent scout may be represented by an authorized agent. An authorized agent is defined as a sibling or a Cub Scout of similar age.
  • Cars in the current year competition must have been made for this race season. Cars or parts of cars such as wheels or axles, from previous years may not be used.

Length, Width & Clearance

  • Maximum overall width (including wheels and axles) shall not exceed 2-3/4".

  • Minimum clearance between the bottom of the car and track shall be 3/8" so the car will clear the center guide strip.
  • Maximum length (including wheels) shall not exceed 7".
  • Maximum height shall not exceed 3".
  • The wheelbase (distance between the front and rear axles, center to center) may not be changed from the kit body distance of 4-3/8". The official kit block has pre-cut slots which are correctly spaced. If desired, these slots may be pre-drilled before they are used or straightened if they are crooked.
  • 100% of the car must be behind the starting peg.  NOTE: Our track uses a center of lane starting peg which needs to be accounted for in race car design.
  • Details such as steering wheel, driver, spoiler, decals, painting and interior details are allowed as long as these details do not exceed the maximum length, width, height, and weight.

Wheels, Axles & Bodies

  • Car bodies must be from the block of wood in the BSA Pinewood derby kit.
  • Only the wheels and axles from the official Cub Scout Grand Prix Pinewood Derby kit or official BSA Pinewood Derby wheels (any color) may be used.
  • Wheels and axles not from the official kits are prohibited.
  • Wheels and axles which have been modified by other parties are prohibited, even if they are BSA Pinewood Derby wheels.
  • Axles must be mounted into the wood. Either end of the car can be the front.
  • Axles and axle heads may be filed or sanded to remove flashing and burs, then polished to reduce friction. No dimension changes or reshaping can be made. This light filing, sanding and polishing is the only axle modification allowed. Beveling, rounding, tapering, thinning, grooving, or any other significant altering of the shape or performance of the axles or axle heads such as "speed axle" modifications is prohibited.
  • • The outside circumference of the wheels can be lightly sanded to remove surface and casting imperfections. The tire treads on the outside of the wheels must remain visible around the entire circumference of the wheel. The outside of the wheel cannot be sanded and the words “BSA Pinewood Derby” must remain flat, visible and untouched.
  • The hub may not be changed or modified in any fashion. Beveling, rounding, tapering, thinning, perforating (drilling), or any other significant altering of the shape or performance of the wheels or wheel hubs is prohibited.
  • Modification of the cylindrical inner wall of the wheel which contacts the axle such as tapping threads into the hub is prohibited.
  • Wheel bearings, washers, or bushings of any type or fashion are prohibited. This includes "wheel covers" which serve to keep the wheel hubs from contacting the car body. It also includes "hub caps", or anything else that might serve as lubrication "well"
  • The car shall not ride on any type of springs.
  • The car must be free-wheeling with no starting device or other propulsion, such as adhesives, magnets, rubber bands, motors, jets, etc.
  • Metal frames and metal axle supports are prohibited. The aftermarket plastic axle supports are also prohibited.

  • The car may be carved, cut, sculpted, and/or sanded in order to enhance performance and/or appearance.
  • No loose materials of any kind are permitted on or inside the car.
  • Additional materials may be added to the car for the following purposes only:

  • A car may be lubricated before registration and weigh-in. This is the only time when lubrication is permissible. Specifically, cars may not be lubricated while competing during the race or at the time of a repair during races.

Ground Rules

  • If a car jumps off the track before the finish line, the heat will be run again. If the same car jumps off the track a second time, the heat will not be run again and will automatically lose the heat.
  • If a car leaves its lane and interferes with another car, the heat will be run again. If the same car leaves its lane a second time and interferes with another car, the heat will be run again without the interfering car. The interfering car will automatically lose the heat.
  • If a car suffers a mechanical problem and a repair can be accomplished within five minutes, the heat will be run again. If the repair is not feasible or would take longer than five minutes, the car will automatically lose the heat. If needed, the heat will be run again without the damaged car.

Dress Code

  • Scouts should be in Class A uniform during the competition.

Inspections and Disputes

  • Each car must pass inspection by the Inspection Committee Judges before it may compete. The Inspection Team has the right to disqualify those cars which do not meet the rules.

To be included in the race, the modification must be completed prior to the end of weigh-in
  • Interpretations of the rules described herein are at the sole discretion of the Inspection Committee Judges present during the Registration and Inspection process.
