Autocross tire pressures

[j.fro]

Ahhhh...
I start 1st run at those pressures, reset to those after first sand second runs, then possibly adjust in later runs. On a typical 90 degree day, I gain 2 psi all around on he first run, about the same on the second, 1 psi for the third. Then it's usually time to break out the sprayer to cool the tires, and things stabilize.
Brad, just to give a bit of info, Kenny Schreeves and I set the alignment two years ago. Last year I took a PCA regional AX championship, NASA Mid-Atlantic class and overall champs, and SCCA regional F-Prepared champs. The setup seems to be working really well!
