Draglite backspacing?

Joe 5.0 said:

Looking to buy a full set of either draglites or prostars and want to make sure they'll fit before I buy them. Plan on going with 15x3.5 up front (w/26x4.5 et fronts) and 15x9 out back (w/275/50 et radials).

Whats the proper backspacing for them to not rub, and more importantly go on without brake clearance probs? Brakes are stock, and will only be replaced with OEM sized stuff (not cobra stuff).

I would go with the 15x10 outback. They look alot better. 15x10's fit fine over the rear brakes. I'm running 275/50 ET radials, the passenger side rubbed just a tad on the exhaust, just had to bend the exhaust a little bit and everything was fine. I forgot what my backspacing was, I think it was 5.5"

For the fronts to fit you'll need to grind on the brake caliper in a few spots. The crossbar on the caliper will rub on the wheel. I'm running a 3/8" spacer up front and they still rub. I just cut that bar off with my grinder, I was told thats OK to do, but my brakes are making some funny noises, not sure if its because of that.

See if this helps
