Wheel and tire size for GN

[fastiroc]

Looking to order some wheels for my Grand National. I would like to run a 18X9 for the rear and 7's or 8's in the front. Does anyone have any tire size recommendations that will work with that combo. I am proabably going to order to boze wheels. Does anyone know right off hand the backspacing that will work on the G body's. I think it is 4.75 but I will have to measure it to be sure.

From what I've heard/read.
Rear in a 9" width should be 4.75
Front in an 7" or 8" width should be 4.5

That sounds good.

Thanks Eric, your car looks sick and I have seen it on turbo buick. I seen where some people have run a 18X9.5 with a 5in backspacing. Is that possible. That of course was a 1 piece Coy C5.
