Don't ask me why i know, but the Michelin Pilot as3 works best at the track at around 38 or 39 PSI, hot. The sidewall is far too soft at any pressures lower than that.
But the federal 595 rs-rr seems to work best with 35 in the front, 36 in the rear. Again, hot.
But the ability to put heat into the tire, and thus raise that temperature and pressure, is really going to come down to braking.
Tires heat up from flexing. Yes, cornering loads will Flex the sidewall as well, but most of the flexing happens under braking, especially on low horsepower cars like ours.
That's why I asked what brakes he will be using as well. If he is using something like an oem brake pad, then he is not likely to be able to generate a lot of heat into that tire, before losing his brakes.
Let's not lose sight of the fact that pressure is really secondary. What we are really looking for is temperature. Pressure is simply how we manage that temperature.

Interesting choice running AS tires on track as a regular course.
Anyhow, most novices will heat up tires more via cornering versus braking.
Regardless, the ever so simple rule to follow (except when behind wheel - LOL) is your tires capabilities are 100% the sum of the following accelerating + braking + cornering. The combination doesn't matter the tires cannot exceed 100% sum.
Good luck
