I should also share what I've learned so far on optimal tire pressures. My first track day I ran the manufacturer recommended 32psi front/39psi rear (cold). This didn't feel great, so for my next track day I started with 34/36 (cold), which was better.

My 4th track day, I moved to setting hot tire pressures with a target of 38psi front and 40psi rear after a full session based on my instructor's guidance (he was driving an E46 M3). That setup seems to be ideal with good balance, steering feel, and tire shoulder wear. I measured the tire pressure cold the next morning and it had fallen back to 32/32.

Going forward I'm planning to run 34/36 (cold) for street use and 32/32 (cold) before a track day and then adjust as needed to keep the tires at 38/40 (hot).
May I ask what your wheel set up is?
