I have found that many people don't consider a rub a rub. If it rubs while cornering hard or with people in the back but it is fine going straight than to me, it rubs. You can run more camber in the rear and see if that works, but unless you get more camber up front which you can't do stock, then you will understear alot more. I do some track work and go down to the dragon and have no interest in any rub. Have you contacted Zoeb to see if he will let you swap the rims? LTBMW likes to really stretch tires to make M3 offsets work on lowered cars but I think that doesn't look right. What tire do you have on? 275 or 265?
