The types of wheels used on soap box derby cars have changed significantly since the first racers coasted down that hill in Ohio in 1934. Buying the appropriate wheels for your soap box car will result in more stable handling and steering, not to mention an improvement in aerodynamics.

As there is a limit on size, shape and construction of an official racer, there is a demand that the wheels be officially approved Z-Glas wheels. However, if you are building a racer for fun, or if you want to start at an amateur level and get in some practice before going for the big time, any wheels will do. But some are better than others, and if you're serious about going for the big time, you'll want to get the best wheels you can for your practice sessions.

Your front wheels should be turned so that, if your car were to roll it would turn into the curb. If your car is facing downhill, the front wheels should be turned into the curb. If your car is facing uphill, your front wheels should be turned away from the curb.
