Start with a lower pressure in your tires. They will heat up and get too hard for good traction. And then check your pressures immediately after finishing your session.
I don't think I can make 5/31. (Longevity)

I already changed my brake fluid to DOT 5.1 (AP racing). It isn't teflon but it has an even higher boiling point than DOT 4. DOT 5 is teflon and will not work with ABS, 5.1 is miscable with DOT 3, 4, etc.
The Proformance team disagrees about underinflation. They say to inflate 20% over manufacturer recommended pressure. For us that is 7 lbs over Nissan's recommended pressure of 35psi. I am running at 42 psi all around.
I am using Esther oil. It appears to be good at high temps. By the way, the Michelins barely got warm on the track, not even close to hot. Maybe I am just too slow to really heat them up. Also the Michelins are Z rated. They flex much less than the W-rated Potenzas.
I'm sorry you can't make it on the 31st. Maybe one of these days we can get together.
