Pinewood Derby

The following official rules shall be used for the Pack 112 Pinewood Derby:
New Cars Only
Cars must have been built during the school year which the competition is being held.  No cars from a prior year will be permitted.

Official Parts Only
The official Boy Scouts of America Pinewood Derby kit must be used.  Kits purchased from hobby stores, catalogs, the internet, etc. may not be used.

The weight of the car cannot exceed 5.0 ounces (142 grams) as measured by the official scale used at registration on race day.

  • The length of the car must not exceed seven inches.
  • The car body width at the wheels must be the same as the original kit (1 2/3 inches) and cannot exceed 2.75 inches overall.
  • No part of the cars body can extend past the starting pole while staging the car before the race.
Wheel Placement
  • The wheels must be mounted in the slots pre-cut in the body of the kit.
  • The clearance between the car and the track must be at least 3/8 inches.
The open practice session will be valuable for this.  If the car is too low, it won't clear the track and won't run.  There will not be time on race day to make adjustments.

Wheels and Axles
  • Only official BSA Wheels provided in the kit may be used.
  • Wheels may be lightly sanded to smooth out mold marks ONLY. No reduction in width or diameter or change of shape is allowed.
  • Axles provided in the kit must be used.
  • Axles may be filed or polished to remove imperfections.
  • Wheel bearings, washers, bushings or springs are prohibited and will disqualify the car.
  • Only DRY, powdered graphite or Teflon white lube may be used to lubricate wheels.
  • No lubrication may be applied after the car has been impounded. 
Cosmetic details such as steering wheels, decals, paint, etc. are allowed as long as they do not violate length, width, weight, or other specifications listed in the car kit.  All must be firmly attached.  Cars with wet paint will not be allowed to race.

Each car must past inspection by the Race Committee.  If a car fails to pass, the scout will be told the problem(s) and corrections may be made.  Bring tools and spare parts just in case you need to make some last minute adjustments!


Race Procedures
  1. Good sportsmanship is expected of all Scouts and Parents!
  2. We have an aluminum 6-lane, 49 foot long track for the competition with an electronic timer/scoring system.  We will also be using our Gran Prix Race Software to randomly set-up each heat race and record the results.
  3. The racers will compete in heat races of up to six cars.  Finish order will be based strictly on total elapsed time for the heats.
  4. At the completion of the heats the total elapsed time will be calculated with the highest heat time for each car being eliminated.  The car with the lowest total elapsed time will be declared the winner.  This insures each competitor at least 6 heat races.
  5. The first, second and third place winners from each division will then compete in a final championship race at the end of each session.  The winner of this race will, once again be awarded to the car with the lowest total elapsed time.
  6. If a car jumps the track or interferes with another car, the heat will be rerun.  If it happens on the second run, the car will be eliminated from that heat.
  7. If a car is eliminated from 2 heats, it will be eliminated from the race.
  8. If a car breaks down or loses a wheel, the owner will be allowed three minutes to perform repairs and the heat will be rerun.  If it breaks down a second time or cannot be repaired, it will be eliminated from the heat.
  9. After inspection and impoundment, cars may not be handled by anyone other than a race official except to perform repairs allowed in the event of a breakdown during a heat.
Trophies will be awarded to the 1st, 2nd, and 3rd place winners, along with a Most Creative Design and Best Scout Theme award in each division (Tiger Cubs, Wolves, Bears, and Webelos). The awards for the category of most original/creative design and best scout theme will be at the sole discretion of the judges.

All participants that do not win a trophy will receive a participation ribbon to recognize their efforts in this year’s derby.
