I'm not going to go into any long speach on how f***ed these rims were spec'd out. Bottom line is if you want to look cool and putt around like you got a 4cycl. Buy them. If you want to drive the way the car was designed then don't. I'm contiplating selling and going back to stock so I can drive the car prior. Yes I've done spacers and adjustments,still rubs(scratched up side walls look like chit) in hard corners, $250 a hoop and it gets old real fast.
For the sake of others reading this thread in the future, I think it's worth nothing that there are a number of other folks running the Forgestars who don't have all of these fitment issues. I'm not sure what the issue is - alignment and ride height, perhaps?
