Best Tyre pressure for 993

[veewhy]

I have a standard 993 with 18" Bridgeston S02's. Does anyone else have similar?, if so, what tyre pressures do you use?.

Also, what pressure do other 993 owners use on theirs?

I run

Front = 36psi
Rear = 42psi

If I put anymore in the rear's it tends to make the car too 'jumpy' at the front, If i use less it affects the crossover point from under/oversteer to the extent where understeer remains for too long.
