These were not shaved, not that you should have to, in order to void serious chuncking. Problem solved with Nitto NT1's.
Just to clarify, this happened running my 3200# Audi Quattro, and not my FRS.
Curious to see reports on trackday tires FRS drivers using...

My stock Michelins look like that after a few AutoX runs.
