Actually I'm not sure why nobody mentioned this but you should pump the tires up to about 3 pounds under maximum (47 lbs if I recall correctly) unless you want to roll around on the tread corners and chunk your tires. Standard pressure simply isn't enough once you push the car in the corners. After your track session let several pounds of air out (~ 5) since they air will be heated/rarefied and you'll have elevated pressures that will promote premature wearing of the center of the tire with normal street use.

Enjoy!
