I'm running 32 psi in the rear and it's hooking thanks to the ever-so-unpopular 30 dollar traction bars :D . I just trip the stage light about as shallow as I can. I have the front tires at 35, and I could go more but when I get to the strip (I drive 1 hour to get there) I do nothing to prep the car. All I do is allow a 20 minute cool down period, and then I turn the key and stage it. A true, 100% in street form car.
