Autocross Cold Tire Pressure

[ZeroGSR]

What is everyone running as their cold tire pressure for Auto-X on the stock tires? Was going to start around 38psi front, but wanted to see if folks are leaving the rears at stock pressure or bumping them up a bit as well, or going as high as 41 in the front like is recommended for high speed driving (which is still 33 rear).

I usually start at 32-33psi cold for auto x. Once they heat up they get up in pressure pretty quick.

38 cold for the front sounds like a good starting point. The PS4Ss don't have a very stiff sidewall and if you're pushing the car, you'll get some roll over onto the sidewalls. Rears can go either way to play with balance, some folks like to run lower pressures to get more rotation, but you can get the same effect running higher pressures, more preference and how the tires are wearing IMO.
