It's been ages, but I think I treated them just like an RA1. 32 cold looking for 36-37 hot.

a few years ago I was using the Proxes on my 93 Miata depending on how cold it was I would shot for 32 hot pressures.
I found 36 was to high of a pressure on my car.
most of the time in the middle of the summer I would start at 21 LBS cold and I would get to the 32 I was after.
in spring and fall when it was cold I would have to start at about 25 to 28 cold to get me to the 32 hot pressure.
all this depends on the track temp how hard your using the car and the type of track your at.
a track like LRP your only using your brakes twice compared to say NHMS were your on your brakes lots more often. your brakes will heat your tires faster then your tires just rolling thru a corner. it's as simple as heat transfer.
