I drive a 2004 base Boxster in PCA S-01 class. This is a stock class that allows you to use any of the tire/wheel combos available for that year. A 1999 Boxster in my class has the same wheel and tire diameter,and the same Potenza RE-11's, but his track is obviously much wider in the rear than my car. I believe he is using spacers to increase the rear track and get better grip. Would this not bump him into a modified class? He is a veteran auto-xer and consistently fastest in this class, in fact, faster than Boxster S models in S-02 class. I read the auto-x rules but this isn't specifically addressed. What do you guys think? I want to make sure there is an even playing field. Thanks for any insight given.
