What tires would help. What wheels and size. What suspension etc....
The best way to measure pressure is to use a needle pyrometer which you stick in the tire right after your run. You take temps of the inside, middle and outside tread of the front tires.
If it's even across it's perfect.
If it's hot in the middle you have too much air.
If it's hot on the shoulders you need more.
Then you adjust the rear pressures to your liking.
