Ran yesterday (boy was it hot too). Started at 42F 36R, which worked fairly well - began watering tires after run 2, rechecked pressure after run 4 saw 44 F and 38 R -> reset to 40F and 36R---gained almost a second by run 6 (some of that came with course experience by the 6th run too).
I also just installed a big honkin 32mm ACME sway bar which helped considerably -barely saw any scuffing on outside edge of tires.....
BTW ---> 78 drivers -- I was 11th pax/24th raw
