This should be a fun event for all involved. If it isn't maybe you're doing something wrong. There will be only one fastest car but that doesn't mean that everyone else's effort was for nothing. Competition is a good thing. It builds character, teaches us about our temperament and brings humility. Reading this text will not make your car fast but using it can make you and your car more competitive. 1. Fast cars usually have a low profile that offers the least resistance to the air-stream. Character figurines glued to the car and other excessive trim can slow down a car, even if just a little. The aerodynamics of a car can effect the car's performance but it is not the highest priority.2. Axles. The "nail" axle out of the box will look pretty bright and shiny but its appearance is deceiving. First, it will have at least two metal webs that reach from the nail head to the shaft. These are small but will ride next to the outer wheel surface. Use a fine mill-cut file to remove these webs. Mount the axle in a drill motor or drill press and rev it up to perform the filling tasks. Next, you'll find that axles are out-of-round by as much as 2 to 5 thousandths of an inch. Again file them to make them regular then use 400 grit wet-n-dry sandpaper with water or light oil to polish them back out. Axles should be polished to provide a surface for the wheel to roll without restriction. 3. Weigh the car to the maximum, 5.00 ounces. The higher mass per volume helps overcome drag and friction. If your scale isn't extremely accurate provide an easy way to add or remove weight on race day. Try using wood screws with washers under them you so can add or remove the washers as necessary.4. Try putting the weight towards the rear of the car. It won't make a huge difference but then every little bit helps. The theory is that the higher weight pushes the car for a longer period of time. 5. Insure that your car is tracking straight. A car that bumps the lane guide more often gets slowed down more often. A "front-end alignment" may be necessary. 6. Use a good dry lubricant. Dry graphite seems to still work better than the white Teflon compounds now available. 7. Insure your wheels roll smoothly and are not binding. A good test is to spin each of your wheels with your finger and let them run to a stop. It should take 20-30 seconds for well tuned and lubricated wheels to stop completely. You may want to rub some dry graphite on the surface of the car body where the inner wheel hub touches. 8. Never, never, never roll your competition pinewood car on the ground or concrete. These rough and dirty surfaces can ruin the car's wheels, axles and alignment..

Let's state right here and now that its the fun of working together, learning and the sportsmanship in racing that's
really important in the Pinewood Derby event. This should be a fun event for all involved. If it isn't maybe you're
doing something wrong. There will be only one fastest car but that doesn't mean that everyone else's effort was
for nothing. Competition is a good thing. It builds character, teaches us about our temperament and brings
humility. Reading this text will not make your car fast but using it can make you and your car more competitive.
