My track is pretty tame compared to the ones you drive on. THAT IS WHY i DON'T HAVE THE SAME ISSUES<stupid caps to lazy to retype> as some of you with the rims cracking. My rims are in tip top shape and I ran a race on a set of advids with no problems with the bearing after. I didn't grind my arms, I let the rims do it lol. I run the +2 hubs as well.
