Thanks to Alex leading the way in his new 992 GT3rs, he has already done sub 50s earlier in the day, crazy fastttt.

The Z06 did not disappoint, I was hoping it could do sub 55 at Buttonwillow, considering the car is still on PS4S runflat tires. I did 3 sessions in the afternoon, and shakedown was already a 1:53.55.

Now the car is modified, front & rear Giro rotors, GP40 pads, feels great.

PS4S on the 7th heat cycle, and about 500 miles street driving.
