Hey Man, Thanks for helping out on the forum, I appreciate it.
I was curious though.... You're running a 17x8.5 +15, but are you running any camber shims or just stock?
I am running 17x9 +17 in the rear and will be on air as well. I am assuming I will need a -3 shim.... -5 is A LOT for camber, IMO.
Anyway, thanks again.. Hope to hear from you soon.
