i know the car has more time in it, and i know i have a lot yet to learn, but i ran a 2:15 up at Thunderhill yesterday, with consistent low 2:16s in clear laps. I've had 3 track days up there in as many weeks, and each day i dropped like 3-4 seconds off my time.
biggest gains were found in turn 1 (turn-in at 4500 rpm in 5th) and 9 (surprisingly high speed 4th gear). i know i'm leaving time in 6 (which is random, but i find it a hard turn to read), and i know i'm not braking late enough into 10.
no offs -- only one half-spin over the cyclone which i caught -- and the car held up beautifully. new (bigger) oil cooler opening left me with 220 and 230 oil temps at the end of a 30 min session in 100 deg. no problem with brakes at all. 710s get pretty greasy in that heat after a few laps, but they have held up okay. i should get one more day out of them.
i also rode in a track-prepped CaymanS yesterday -- which was.... underwhelming -- especially after the gearbox broke, and IT CAUGHT ON FIRE.
good times.
