Setting pressure by tire temp resulted in my best lap times.
I don't have a temp guage but I found running 30f/32r hot at Fontana ACS provided the most even stock tire wear while providing a decent grip level. Back end was really loose at 38 hot during my very first session experience.

There is plenty of tire temp data on the track day video thread elsewhere on the forum. The consensus to date indicates with the MPSC2 the fronts need to be around target range 29-30 hot F and 32 R
