2005 Pinewood Derby Participant Rules
Read the rules and specifications found in your kit. Also, read these rules provided
by the derby committee carefully.
PACK RESPONSIBILITIES
The pack should retain all winning cars that will compete in the District Pinewood Derby.
This ensures that the cars are in the same condition as when raced at the pack level. The
Scout and his family should ensure that the cars to be entered in the District Pinewood
Derby meet the following requirements.
CAR SPECIFICATIONS
1. Width - The overall width of the car shall not exceed 2 ¾”.
2. Length - The overall length of the car shall not exceed 7”.
3. Height “ Though BSA rules do not specify a height limit, the track design prohibits cars with a height greater than 3 ½” from safely running down the track.
4. Weight - The weight of the car shall not exceed 142.0 grams (5 ounces).
Cars will be weighed in on race day using a calibrated scale.
NOTE: CARS THAT EXCEED THE ABOVE WEIGHT ON THE OFFICIAL DISTRICT
SCALE AT RACE DAY REGISTRATION WILL NOT BE PERMITTED TO RACE
OVERWEIGHT. WE WILL ALLOW WEIGHT TO BE REMOVED FROM THE CAR
PRIOR TO FINAL CHECK IN BY THE SCOUT AND HIS FAMILY. HOWEVER, NO
WEIGHT MAY BE ADDED TO AN UNDERWEIGHT CAR.
No loose materials of any kind are permitted in the car. The car may be hollowed out and
built up to the 142.0 gram maximum by the addition of weights, provided any additional
material is securely built into the body of the car.
5. Track Fit - The car must be constructed such that it fits the track. This means that it
must straddle a lane guide which is ¼” inch high and 1 5/8” wide. The car should be the
original width of the block at the axles and have a clearance of 3/8” from the ground. The
car should be a maximum of 7” long, 2 ¾” wide, and 3 ½” high.
6. Wheels and Axles Only the official BSA Pinewood Derby wheels and brad style
axles supplied in your kit are permitted. The addition of spacers, washers, and bushings
is prohibited. Axles must utilize the existing axle slots in the car body. The axles must
be visible and cannot be covered by tape or any other material. Burrs may be sanded
away from the plastic wheels, but excessive removal of material to “crown” the surface
of the wheel that meets the track will not be permitted. Axles may not be plated.
NOTE: THE BSA SIGNATURE ON THE WHEELS MUST BE VISIBLE TO THE
JUDGES AT THE REGISTRATION DESK. ANY CAR, WHICH
INCORPORATES ANY WHEEL OR AXLE COMPONENTS NOT SUPPLIED IN
THE OFFICIAL PINEWOOD DERBY CAR KIT, WILL NOT BE PERMITTED
TO RACE.
Only dry graphite or white dry lubricants are permitted. Lubricant may be used prior to
inspection at the race location. Once inspected no additional lubrication will be allowed.
7. Other Attachments - The car shall not ride on any type of springs, or incorporate any
other devices, which might aid in its travel.
8. Details - Steering wheels, driver decals, painting, and interior details are permissible as
long as these details do not exceed the maximum length, width, and weight
specifications. Make sure they are adequately secured to the car.
NOTE: METALLIC SILVER PAINT IS NOT RECOMMENDED. THE SENSORS
ON THE TRACK CAN REFLECT OFF THIS SURFACE AND CAUSE TIMING
TO BE INCORRECT.
9. Inspection - Each car must pass inspection by the official inspection committee before
it will be allowed to compete. The inspectors have the right to disqualify those cars that
do not meet the above criteria. No physical alterations may be made. No additional
lubricant may be added to cars after inspection.
