Track setup.. tires/psi etc

[2manywheels]

Out to the track tomorrow.
Not an autocross. But full sized with a 1/2mile straight away.. and some decent fast corners..
Besides checking everything over(torque/brakes/lines safety etc..)
What should I start with for tire pressures?
Supposed to be 20 degrees tomorrow and dry.
Cold, they are currently 32.5psi(Dunlop Direzza's) 205-50-15's on the 15"x7 Enkei RPF1's.

I have a tire temp guage I will be checking between runs to check for higher heat on different parts of the tire etc.
I have never taken a FWD car around this track. Only rear drive ferarri's and vettes.
Any thoughts or suggestions?
