If you are running the standard 19 & 20in wheels and OEM tires the optimum pressures on a track are 37/38lbs for the front and 35/36lbs for the rear. These are hot pressures while on the track, not DD street pressures. Street pressures are 32lbs square. Before the first session of the morning adjust the pressures to @ 5/6lbs below the desired hot pressure. Immediately after returning from the track to your parking area adjust the pressures up or down to the target pressure. Do this after every session.

Flush and refill the brake system with high temp fluid.

You will be inside a car with a windshield. An open face helmet will be just fine. The choice is yours.
