I wonder how many heat cycles these can take (anyone??). It seems they will still have plenty of tread depth well past their heat cycled out!

With my 991 and 70-80* weather, 35f / 35r has been best. They don't get greasy and hold well. Camber is 1.9 both ends. Allan

I like how my GT3 drives @ 33/36 hot. I've tried various combinations and it always seems to work better with around 3psi extra in the back tires. I put 10 track days / 600 track miles on the car last season and the tires are still over 50% I think.

I found 35 f/38 r hot works for me on the MPSS. I have alignment setting of -2.2 front, -1.8 rear, and pyrometer reading seems even for all 4 tires.

I have identical camber settings on my 997.1 GT3 and the "optimal" pressures I have arrived at by seat-of-the pants methods (36F/38R) are almost identical . I also have nearly 2000 track miles on the MPSS and there is still some tread left although the rears are nearly gone.
