Stupid rules we run in PCA (and SCCA) we take serious points for every 1/2 inch over stock. So.. we play by the rules and pull out every single wheel offered and submit it to the rules makers ""HERE"" look.. the car had this optional wheel... :) << speaking to rules maker.

Here are pics. One shows the scrape on the spring perch. Another pic shows the width and offset (8" and 57mm). The tire is 235/40 18. Now I have 225/40 18 which fits but is less than optimal for track (HPDE). I have -1 camber up front and sadly -2 in back (couldn't get low toe in without leaving too much negative camber).

Buy 17's.. No other way besides going to a real shock with the smaller perch.
