They actually arent very wide. They are 26x10.5x15, but I think they are only about as wide as my 275 Nittos plus I ditched the spacer in the back, so they are tucked in and look smaller than they are. Its okay though- I'm sure they'll hook well enough to break stuff :rockon:
No grinding at all. They are 4.5 backspacing. I think I may have a foxbody rear in it though- the wheels are tucked about an inch more than i thought they would be. Still have Cobra brakes on the back though.
