There are plenty of threads on track tire pressures, but only an occasional mention of autocross. Most of those indicate that autocross pressures should be about the same as for track (30F, 32R).

Seems like a reasonable starting point, but I'd like to get more input.

For autocross I've had success running hot pressures of 28F 29R on MSCP2's. (Neg camber on my car has been increased to -2.25 F -2.5 R) Using the circuits mode makes it easy to monitor pressure during the course of the day. No sidewall rollover, good grip. I think you can get away with a little lower pressure for autocross because you don't have the same high speed loading you'd get on track. By comparison the previous MSCP's liked to run 32F 33R hot but the MSCP2's feel greasy at those pressures. My $.02.

I've been using 28/29 but on my last autocross day I was finding 29/31 to feel pretty good.
