Assuming outside temp around 75F degrees, I'm guessing your front tire is warming up to around 40psi. I've seen as high as 6psi raise in my front on a hot day and hard riding. Normal increase from cold to warm for me is around 4psi front and 3psi rear. Approximately...
I found with my q2's, and also with my new s20r's, the tire performs best for me at around 28-30r & 32-33f when all warmed up.
Assuming it's about 80 degrees outside, I set cold pressure around 26rear and around 29front.
But- I don't brake anywhere nearly as hard as you do, so some difference there I guess.
I know that sounds low, but that was my experience after continually adjusting down over two years. I used to run around 34r -35f cold. Yeah the tires still perform fine, but don't feel as grippy. I suppose the contact patch is smaller the higher the pressure.
This is all street experience, not track. Using a Motion Pro digital gauge, with calibration reset capability. I trust the readings I'm getting.
