Message PSI in the front. Overstreer, a couple PSI in the rear. Ambient temp and tire condition and type (Max performance... R-comp... Full slick) have a lot to do with pressure settings as well. Also driving style. I know folks who never worry about tire pressure for the entire track day as temps change and they drive to suit. Others obsess about every 1/2 PSI change and are continually adjusting in the pits.

Need to run a couple of sessions, see how the car feels and adjust settings between sessions to see what works. If the temps are getting high and pressures are climbing, drop down a couple PSI if the car is starting to slide out more.

Sorry, it's not an exact science.
