What online companies offer tire shaving of competition tires? Or do all the big boys (TireRack, Discounttiredirect) do that? I just ordered a set of A6's and I was mostly motivated because they didn't require anything other than heat cycling which of course TR offers...

 

Tirerack does shaving but I don't think you need to shave A6's. Or any tire for that matter, there was an article in sportscar magazine about tire shaving and it really didn't make much of a difference, .02 sec. Which could make a difference if your class is really close.
