2001 996 C4 Tire Pressure for DE events

Wheels and Tires

Vehicle Information: Model: 996 C4; Year: 2001; Body Type: Coupe; Total Mileage: 30,000 miles;

I know you have covered tire pressures on 996 multiple times, and have taken the time to read all the previous posts going back to 2001 before sending you my questions. I also have purchased a high-end pressure guage going to 2 decimal points. I also understand different tracks, weather, and driver experience play a vital role in selecting the best tire pressure.Im running Michelin PS2, 225 265 on 18's . 36F/ 44R PSI. Car is stock.However I havent found responses for the following questions;1. Why have different tire pressures for the front vs rear on a 4 wheel drive car on the track? 2. The tires usually gain 6+psi when hot, bringing up the rears to 50PSI, What hot tire preassure or top range do you recommend for DE events for this car? I have gotten everything for 5 lbs over stock, to 26 cold all around.. 3. My engine temp has been rising over 200F at DE events. At what point should a center radiator be installed?Joel, thanks very much for your help, as i'm clearly confused on tire pressures for track days.
