Track Day Tire Pressures
What tire pressures are people running on track days. I have gone from 32 cold down to 26 and don't seem to get consistent results. My fastest day was the first run in the morning at 32 cold. On another day I ran 32 hot and didn't go very fast.

A buddy of mine on this forum recommended I put my Hankooks down to 25 psi. I noticed results.

I run my rears tires about 1-2PSI lower (hot temp) than my front tires. This seems to balance the oversteer/understeer problem better. If you have stock camber plates and can't get enough negative camber, or want better turn in, this may help. Check for side wall roll over on each session and adjust accordingly.
