Kris,
I agree with Greg. I've driven my Cayman S to/from a few big track events on Nitto NT-01s with no issues. In fact, I even measured the tread with a depth gauge to see how much wear there was from the ~200miles of street driving to get to the track, and it was basically zero (less than 0.1mm). The amount of wear I measured for my Cayman during the track portion of the weekend was usually between 1-2mm total, depending on the track.
So, as long as you are starting with tires that will comfortably pass tech, you should end up with plenty of rubber left to get you home. Just keep an eye on them, and maybe swap left/right between Saturday and Sunday.
I also don't believe people that claim a heat-cycling issue for highway driving on most R tires. Out of curiosity, I measured the temps on mine immediately after exiting the highway, and they were barely elevated (something like 10-20F above ambient, compared to a ~100F increase for spirited track driving).
