Overnight the temps at the VIR track dropped in the 20's, which made the track cold and I found out the hard way that the Goodyear F1 GSD's don't work at all when the temps are even in the high 30's or low 40's. Guess that why they say it is a Summer performance tire...

Went off the track in the same corner, correctly named the "Left Hook." All four tires gave up on grip and I slid off. Recovered with no damage to the Z, but a big blow to my driving ego.
It was a great charitable event and there were plenty of Vettes there. The oldest was a 63 split window with a 386 with two 4-barrels, otherwise it was all original.
The event gave you 15 minute sessions, which is about 4 fast laps around the 3.27 mile track. Not racing speeds but I was well over 100 in certain sections of the track. Grrrrrrrrrrrrrrrrreat Fun!
