I was running 36 in the front and 32-33 in the rear on my Mazda3, and when I went driving in the Mountains were heat would build up with Spirited driving I would lower the fronts to around 28.

 

Sorry, I don't get that at all; if anything, lowering the tire pressure will increase the heat build-up in the carcass of the tire.

 

The first time I went up at 36 PSI after a few runs on the Dragon I was pushing badly going into corners, checking the pressure at that time it was over the 50 PSI my gauge read. The next time I went up I lowered the pressure to 28 PSI and even after a couple of runs it lost the pushing feeling it had before. Checking with the same gauge they were at 44-45 PSI.
It was not the heat build up that was hurting me, it was the pressure build up because of the heat. More pressure, less tire on the road hence the lowering of the pressure to compensate for the sliding of the tires into a corner.

 

Hmmm, I've done a pretty fair amount of weekend racing in my past and I have a number of friends that still do and I've never heard of a FWD car that ran good times with the front tire pressure so low. I'm thinking that 34psi is the lowest I've ever heard of, and that was on a very tight course.
