You have to have a narrowed rear to run that back spacing i read a thread on it recently look up narrowed rear in the wheel section with welds an the other one was with a billet specialties. You need different back spacing. With a 6.5 you'll grind a little bit, but with a 7.5 there isn't any grind maybe scratching the surface if any. My buddy just told me that with a 8 inch wheel, 7.5 backspacing an to go with a 27/11.5/15 hoosier you should be ok. They told me the wider the wheel the more the back spacing an the wheels lip will get more shallow.
Whoa, what? Draglites do not clear rear LS1 calipers fine. At all. And with a 15x10 wheel you need a 7.5" backspacing or it will look weird; a 6.5 backspace will make them stick out. Even then they won't clear the calipers; you have to grind like a sonofabitch no matter what. A 15x8 wheel will require a 5.5 backspace.
Maybe I'll see ya on some Speed cruises.
