I am sure that everyone has seen those SUV's with the rims that continue to spin when the vehicle is stopped. There is a guy that works in the same building as I do that has an Audi S4 with those rims. The other day I parked my car and I saw his car a few stalls away from mine. I went over and spun the rim, and was quite surprised to find that the free spinning part of the rim weighed a few pounds. Does anybody know how this would effect handling at higher speeds?
