I am going to Summit in 2 weeks to do the NCCBMWCCA 2 day driving school. Today I mounted a new set of Falken AZENIS RT-615 205/50R15 on Team Dynamics Pro Race 1.2 - 15x7 wheels. I will be using these for both days of driving. I plan to – scruff - them a bit before track day (under the cloak of darkness!!). My 87 325 IS / E30 has the suspension done to Spec E30 with Bilsteins and H&R springs, and centered urethane control arm bushings. I have new ATE rotors and I am using Hawk Plus pads. The rest of the car is mostly stock with new exhaust, belts, fluids, hoses, clamps, filters etc.

Now what would you consider a good tire pressure to start off the Summit session with considering this setup?
Any tips for hot or cold temps?
