18" wheel backspacing

[Momar]

I plan to run 18x9.5 in the rear, and wondered if it is possible to fit 18x9.5 in the front also. I know I have seen people run 18x9.5 w/ 18x8.5 in the front, but didnt know if the 9.5's can be made to fit up front. I have priced out '06 z06 brakes w/ my discount, and am considering doing that, but would need a nice set of wheels.

Thanks

Anybody? I am looking at a set of 18x9.5" z06 replica wheels. Anyone have any idea for front backspacing?

Momar, I have 18 rims on my car. They were on there when I bought the car.
I really know nothing about what backspacing the rims are. They are 18" ROH RT Rims. The fronts are model # RT188B00P and the rears are model # RT189B00P. you may be able to call a tire/rim store and they could maybe tell you the backspacing of those rims. I am running Sumitomo HTRZ II 245/40ZR 18 on the fronts and HTRZ II 255/45ZR 18 on the rears with no problems. Sorry I don't have all the info you are looking for.

Well, from what I have read, a lot of the guys are just running 245/40/18 on 8.5" rims. If I am running the same size tire, but on 9.5" rims, does anyone know what offset to use. I know that w/ the 8.5s people are using a -7mm offset, or a 4.5" bs.
