Track Tire Pressures

Hey folks,

While prepping for a track day next weekend, the local chapter says the following about tire pressures, "For the performance driving you will be doing, you should inflate your tire to pressures above those normally used on the highway. With higher pressures, the tires will be able to generate higher cornering forces and will not roll onto their sidewalls during cornering. Recommended cold tire pressures are 38-40 psi in the front and 36-38 psi in the rear."

This seems pretty high: I'm running like 33 psi hot on Firehawk Indy 500's all around when autocrossing and seem to get plenty of grip, and a little higher on the street, where I can definitely feel less grip (then again, the tires aren't nearly as warm).

Thoughts? I know a lot of it comes down to personal preference, but just wondering what others are running and what people think make sense.
