I put on H&R springs on my car...and love it..now..i wanna change the wheel to a 18..but today...when i was looking at it..it seems that it won't fit !!..although i know some of you guys here have great 18s.. care to advise me if it will fit in?

I know it is a dumb question..Sorry..but i am no wheels/ cars frantic

 

If the 18" wheels are sized properly, with the same outer diameter as the stock wheels, then they will not rub unless the stock size rubs now. The outer diameter must be the same on any set of tires you install. ie 205/55r16, 225/50r16, 225/40r18 etc..
