Wheel offset question

[britlude]

My wheel sizes are:

Front 17x7.5 ET38
Rear 18x9 ET42

I think I'd agree that 35 is pretty much the limit - my ET38s are about at the limit of what the front arches can cope with.

and thats with a 7.5 wide,..... OP is talking 8" on the front, another 1/2 inch on each side....
