It really depends on the tire (and type of racing of course, but I'm assuming DE road course stuff?). With steet-ish tires (up through RS3), my car was pretty comfy

It really depends on the tire (and type of racing of course, but I'm assuming DE road course stuff?). With steet-ish tires (up through RS3), my car was pretty comfy at cold pressures in the 28-30-ish range (varies by weather) and coming up to ~37-ish at full temp. With the Conti GT-O slicks I've been setting initial cold pressure in the 20-23-ish range and having them come up to ~30-32. Another guy was running a 370 on Hoosier R6 this past weekend, but he was starting out much higher than me cold, I think 28-30-ish like my street tires? I don't recall how that worked out for him or if he adjusted back down.
