When I switched to the race wingstays (P/N 76101, 76102) with Hoosier R7's this past winter, there was almost no clearance and I'm sure they would have rubbed at the first corner. I was able to bend the wingstays to gain enough clearance that they didn't rub at all at my first track day. I had to bend the arm in two places on each arm of the wingstay. The first bend was to get the clearance to the sidewall of the tire, and the second was to bring the upper portion of the arm parallel to the tire tread. After the first bend, I had to shim between the tire and the arm to maintain the sidewall clearance. It might be an option for you but YMMV.
