I am no expert in this but ill throw some ideas out there.

I know you have a bigger engine in your car and as you know the 911's are rear heavy, my instinct would tell me that the rear tiers would get much hotter than the fronts simply because that is where the power is getting put down and that is where there is most likely more forces being applied from a variety of sources. I would be interested to see air flow over the tires as well, Im sure that the different air flow patterns account for some temperature differences.

I also know that different suspension set ups will improve different things. For example cars that are fast on the straights may not be as fast in the turns so some of your adjustments may be making you faster in the turns but slower on the straights. Some one with more suspension knowledge should chime in here.

Also how are you measuring tire temp? One interesting way I can think is those new fancy laser temp sensors. They care cheap and easy to get and dont actually have to come in contact with the surface to measure temp. I would set up 4 arrays over your tires, connect them to a micro controller (arduino mega should suffice) and log some real time temp data to see what the tire temps are in real time. I would be curious to see if they are getting up to temp in the corners and then cooling off quickly.

Just some ideas.
