Those tire pressures are spot on if you don't over drive the tires.
This weekend I ran the rears at 24 psi. Remember this is autocross not track days.
I got 204 runs and about 4k street miles on these. on the street I run them at 33 psi all day.
Right size rims helps a lot and alignment and the driver.
These are 245s on 17x9 rims. So the shoulder has no pinch and a very slight stretch keeping the sidewalls more stiff. Last year when I ran 225/45/17s on my stock rims I had to run them at 35 psi. When I was driving my FWD car on RS3s I had to run them at 40psi in the front not to roll over.
Andy I will be doing another video with your tarmac prototype springs in the spring.

Those tire pressures are awfully low...
