Official Pinewood Derby Rules
Date: 1/5/07
With the Pinewood Derby just around the corner, it’s time to start building those cars. Here are the rules for construction:
You may use a pre-cut car as long as the wood is pine. Only the car body is to be used. If axles or wheels are used from the pre-cut car kit, the car will be disqualified.
Length and Width
The maximum overall width (including wheels and axles) shall not exceed 2-3/4 inches.
The maximum overall length shall not exceed 7 inches.
The wheelbase (distance and location between the front and rear axles) may be changed from the kit body.
Weight and Appearance
Weight shall not exceed 5 ounces. The reading of the official scale will be considered final. The car may be hollowed out and built up to the maximum weight by the addition of wood or metal only, provided the material is securely built into the body or firmly affixed to it. No liquids or loose materials of any kind are permitted in or on the car.
Details such as steering wheel, driver, spoiler, decals, painting and interior details are permissible as long as these details do not exceed the maximum length, width or weight specifications.
Cars with wet paint will not be accepted.
Wheels and Axles
Axles and wheels shall be only as provided in the Official Grand Prix Pinewood Derby Kit.
Wheels may be lightly sanded to smooth out molding imperfections of the tread area. This light sanding is the only modification allowed. Beveling, tapering, thin sanding, wafering or lathe turning of the wheels is prohibited.
Axles may not be altered in any way except for polishing.
Wheel bearings, washers, bushings, and hubcaps are prohibited.
The car shall not ride on any type of springs.
The car must be freewheeling, with no starting device or other type of propulsion.
Lubrication
Only powdered graphite will be allowed for lubricating the wheels.
Lubrication will not be allowed after the car has been officially weighed and placed in the pre-race area or during the race.
Cars that do not meet the minimum specifications as set forth above, will be given ample time to make the necessary corrections. Once the car is officially checked in and weighed, it will be placed in a pre-race area and may not be altered further.
