I bought a pair of 1 in wheel spacers for the 05 GT wheels that I planned on putting on my 94 vert. I changed my plans and now have 17x8 American Racing wheels with the proper 30mm offset. Now Im thinking about putting the spacers on the rear to even out the track. Ive never used spacers before and am wondering how often I will have to pull the wheels to check them. Anyone who has or is using spacers weigh in on this?
