I agree with this and believe the Z/28 is as good as it is because of the entire package. Look at the lengths the engineers went to; anything that got them a tenth was under consideration. "Flying Car" logic, DSSV shocks, Carbon Ceramic Brakes, the aero package -- and the tires.
I do agree the Trofeo R's are good tires. I'll be interested to compare lap times with and without them. Uh, I guess I mean with them and with another set of wheels/tires...
