So yeah, I have a set of Konig Crosshairs on my car now, and love how the car looks with them, however, I have them in 17's, and they look great, but I want 18's in the rear. Does anyone have any advice about doing/not doing that? I know on the Z's they are like that from the factory and it looks pretty good. The front tires are 225/45. I was thinking about an 18x8.5 for the rear. What's the verdict?
