My only usueful comment is it's silly to have unbalanced hot pressures like that. The only reason is if you have a chassis set-up issue that can only be addressed by staggering the pressures (i.e., sways, spring rates, etc. may be off). The tires have a sweet spot where they tend to grip best when hot, and that is a relatively narrow pressure range. What should that pressure be? Dunno -- try a couple different ones and see. I've heard claims that it is anywhere from 26 - 38 psi... Highly car set-up and driver input dependent.

Not meaningless questions to me, I'd rather go to the track knowing more rather than less about what I'm working with, especially since the temps will be fairly cold.
I'll experiment with the tire pressures, including trying equal front and rear. Recommended street pressures from Porsche are about 6 or 7 psi higher in the rear, so I was considering maintaining a small front/rear difference for the track.
