I just heard that Porsche is using the Dunlop Sport Maxx Race tires and are the only tires option. I was under the impression that the Cayman GT4 were going to use the Michelin Sport Cup 2 tires. Any reason for the change? Were the MSC2 tires too stiff for everyday driving? The GT3RS, Shelby GT350R and Z06 Vet using the MSC2 tires.
