Ok, i am not going to rape the car on the track day, i am just having three sessions of half an hour. so i am not going to be on track all the time..
The track we have here is not very fast, so most of the cornering is slow, like second gear....
I am usually driving 2-3 laps then i cool the car and tyres for 1 lap.. and then again, so basicaly i will drive 10-12 laps max....
Start with about 27-28 psi cold and then measure them after your first session. They should be no more than 32psi hot. The fronts will increase 5-6psi, the backs about 2psi.
