Lifetime of the Wheels

You may have heard that a car will actually get faster after each race. In fact, I’ve actually known people to “spin up” their cars with an electrical tool prior to the race competition, to “break in” the wheels. In this section, we run a car down the track 100 times to see how the car’s run time changes after use. We also look at the effects of periodically adding graphite to the wheel axles. I think you will be very surprised by the results, and the implications for your racing strategy!
