The 2011 GT500's with the SVT-PP have the much better F1 G2 tires. But they are still pretty hard and weak for straight line traction.

I heard the Goodyear F1 and F1 G2 require preheating or just some hot laps before usage... The Motor Trend tester Randy Pobst commented on that as well. When they are cold they are no good.
I hear Michelin PS2's and Pirelli P Zero's are the best non-comp performance tire right now but cost a good bit...
