I felt a little more bumps with my 18s than 17s, but thats hardly the reason why I wouldnt buy the 18s. but for aesthetic reasons, if your going to get 18s, dont get a mild drop (1.5 in.), go with H&R SS or Eibach sportlines. Lo-profile tires and a big wheel gap just dont match. I wish my car would drop about .5 inches more. just something to think about.
