Default Tire pressures

The handbook says 32 PSI all around (cold).
What do you use?

I use 32 PSI in the city.
I use 34 PSI for high speed driving in the country.
I am going to my first track day where +5 PSI is recommended, i.e. 37 PSI.
Does anyone else use more? Or differing front-rear values?
How much should I allow if measuring when the tires are hot?

37, if it's the cold pressure, seems high to me. I've run a max of 36 at the track. If you run 37 cold you'll be in the 43-44 range hot. I'd start with 34 and adjust for subsequent run sessions based upon conditions, tire roll, etc...

When I had S02s I settled on 40/35psi (front/back) cold - worked best for best for me on the road as well as on the track. Anything less than that and I was unhappy with the car.

35 all round here. I find this perfect for me. 34 is too soft, 36 is too hard. Dealer recommended it also.
