I have a 2006 987 S.

Slicks are a different animal and usually run best at lower pressures. They often like 4 degrees negative camber and run 28ish hot. As others have said you will need to get tire tread temps to really dial them in for your car weight and driving style. Many drivers kill off a couple of sets while getting temps and pressures exactly right.
