Jaxgt helped me take the Pista out to CoTA last month. I followed him in the GT, and the Mclarens were delivered to me.
The car is as fast as a 720S/Senna on the back straight at CoTA. It's sprung a bit softer than I'd like, but the grip is there from the Cup 2s. I had all 4 out at the track last month, and it's about as fast on track as the new GT, even though it is 15 mph faster on the long straights. Was just getting acclimated though....spent more time in the McLarens. I'll have it back out there this weekend.
