I do remember saying the instructor thought I was overheating them, we kept on dropping pressure out throughout the day. At the end of some sessions, they were 40-42psi, even when starting cold around 30-32. They would get slick, car would just slide (which is super fun -- but not ideal obviously)...

Alignment specs:
FRONT: Left / Right
Camber: -1.6 / -2.1
Caster: 6.0 / 5.8
Toe: 0.10 / 0.08
Total toe: 0.17
Steer Ahead 0.01

REAR: Left / Right
Camber: -3.2 / -2.9
Toe: 0.18 / 0.22
Total Toe: 0.40
Thrust: -0.02

Another guy was running the 4S's on his Audio RS4, had a similar issue but on the outside of his tires. 4S's def are not track tires -- guess I'll have to see if I can get a new set of tires before next weekend.
