So ive been debating on wether or not i should install some wheel spacer on my 08 coupe? Im thinking 18mm rear and 15 front. Does anyone have them?
You want to do it for looks/stance, performance/handling, fitment of wheels/tires, all those reasons or other reasons?
The short answer is "Yes."
You're probably going to have issues with 15mm front, depending on which wheels and suspension package you have. 18mm rear is pushing it but you might be OK. For reference, I ran 12mm front and had scrubbing issues in my '07 coupe with sport susp.
Good question I don't even know what type of suspension I'm running onwhat did you have on the back?
I ran 15mm in the rear with no issues except over extremely large bumps. Chances are good that, if you have the seats with lower and side bolsters, you have the sport suspension. If your seats are almost entirely flat across the bottom, then you've got the non-sport. Sport Suspension also usually comes with 18" five-spoke semi-concave wheels, but those can be easily optioned on so it's not a guaranteed indicator.
