Yeah I got 8.5" on the front (235 50 17)
Then 9.5" rims on the rear (255 50 17)
This gives me full lock with no scrub, and i can fit a finger inbetween the tyre and the guard at the rear...
Lowering the car will affect the max tyre width also Mark, as mine is only just slightlly lowered at the rear and my 9.5" rims just fit nice...
Note: I have Volk TE37's with correct skyline offset, so the right rims...
