When i was at my first DE event there was alot of discussion around tire pressure. It seems most people started pretty close to the recommended pressure, then as the tires heated up some air was removed. For most 987 and Cayman owners the best place to be was 40 psi for all four wheels hot. Hot meaning after the car has been driven hard for awhile and the air has expanded.

Ultimately, this means we were removing air from the rears b/c they would end up at 42psi plus once hot.
