During track driving, the pressure increases due to the heat. It is normal to decrease the warm pressure back to normal again, not lower than you use on the street. If it gets too low, you start wearing down the sidewalls.
Personally, I don't decrease the tire presssure on the track. I prefer running the pressure too high. It does cost me a little bit of grip and time, but it saves me from wearing out the outer edges of the front tires. I also avoid running very long stints, or else the tires and brakes can overheat. Many short stints are better.
Even better if it rains. Then you can just drive and don't worry about heat or pressures.
