- Wheels must not be modified including the contact area to the track surface; the wheel surface must remain flat.

- Burrs on the wheels may be removed and imperfections may be sanded smooth.
- Wheel bearings, washers, bushings, and modifications to the axle holes are prohibited.
- The car shall not ride on any type of springs.
- Burrs on the axles may be removed and polished if desired. No other modifications such as grooving, tapering, etc… are permitted!
- Dry Lubricant can be applied only to the axle wheel area. No application of lubricant is permitted on exposed surfaces of the wheels.
- Axle wheel covers are prohibited. (I.E. putting hubcaps on to keep the wheel axles full of lubricant).
- Please encourage your Cub Scout to really make a good effort to build their Pinewood Derby racer. The Pinewood Derby requires Cub Scouts to learn the craft skills to build the car, as well as understand the rules of the event.
- Perhaps even more important though, is that Cub Scouts need to understand how to behave and act during the event. They need to be good sportsmen and realize that they did their best and must not feel jealous, or envious of their fellow competitors.
- All adults and scouts are expected to have respect for one another and the competition. Any person acting in a non-sportsman like manner will have their pinewood derby car disqualified.
- The race officials are volunteers for this event. Please respect their decisions. Arguing with race officials is considered non-sportsman like conduct.
