I run 28 F/ 31 R cold. Typically these will increase by 3/4 psi once hot. I found the PSII's very good on track but beware!, they do wear quickly. Out of interest, what track are you to attend?
Ah Croft, it is on my list but living down here on the South Coast does make it a fair old trip. Let us know how you get on and what you think of the car, enjoy
