If your wheels are anywhere from 18 x 8 to 18 x 9.5, they will fit the wheels. This was the 2008 GT500 front tire size, on 9.5" wide wheels. The GT500 wheels were ET+45 (offset), so if your wheels are anywhere between ET+45 and ET+50 you won't have any chance of rubbing. ET+40 would probably work, though there won't be as much strut side clearance.
