I have heard that they are awesome but they dont have a great size selection just yet. If they ever get them in some other oddball sizes I might give them a shot.

Are they now available in Z06 sizes? That's be great if they are, since I think very highly of them. Not only do they handle incredibly well on dry and wet roads, but they are also quiet and provide a very smooth ride - HIGHLY recommended!

I have been running the F1GSD3's for 9 months now and say the following. The new tires are quiter and supply a firm ride. Not as firm as the runflats, but firm. The cornering is better. I can now round a rough corner without alot of sideways skipping. Wet traction is great also. I race my Vette at the 1320 and the best time with the runflats was 13.22, best with the F1GSD3's 12.94. The improvement came in the first 1/8 mile. The last area that I notice an improvement is in the stopping. I can go into a turn hard and brake later now with the new skins. I have the stock sizes all around. Good luck, and if you go non runflats besure to invest in a AAAplus membership.
