The inside rear lip is rolled into itself to create more room so the tire doesn't rub. I paid $100CAD for both at a shop that uses a proper fender roller than bolts to the hub.
that is freakin awesome. but what about this.... what if you tried to run 225/35/18. what whould happen then. im thinking of getting these rims as well but im scared to run 215's. they look thin on the rims.
