4. The car must have 1 ¾” clearance between the wheels.
5. The car must have 3/8” clearance underneath the body.

Why the PineWood Store Makes Pre-Cut Cars... See Point #3
#1 These guidelines are established to minimize controversy over the degree of parental involvement in the construction of the car. Remember that, ideally, the building of a Pinewood Derby car is a father/son endeavor. If a father is unable to assist the Scout in building the racer, help from a mother, older brother/sister, uncle, grandparent, or other adult is encouraged.

#2 Car Design - The Scout should select and produce a sketch of the car design. Ensure that the width of the car is 1-3/4" or greater at the points where the wheels are attached. If the width is less than 1-3/4" at these points the car will not fit on the track.

#3 Shaping the Car Body - In most cases, the adult is encouraged to rough cut the car body. This is particularly true if power tools are used.

#4 Finishing the Car Body - ALL sanding, painting, decal application, or other detailing of the car body shall be done by the Scout.Once the shape of the car body is established it is the Scout's sole responsibility to finish the car. Guidance by the adult is encouraged, but actual performance of the work falls to the Scout. Once again, use this opportunity to instruct the Scout on sanding technique, painting decals, etc., but don't forget to let the Scout do the work!!!
