There are some exceptions such as some R compound tires, Hoosiers, etc
but in general if 40 psi cold is good for you and your driving style/skill level for street then in general you want to shoot for 40 psi hot when on the track. 40/40 rule I call it

Now if only I can find some good 18" tires for
my new car. Wheels are easy in 18 but the 255/40/18 not so much out there that I see, maybe Vredestein sessantas would be a relatively
inexpensive track day tire for this heavy car. My search shall continue

I've always run my audis with one psi greater for the front due to the extra weight.

lbs. and it felt better(oem pzeros), 32-33 is pretty low leading to overheating-blow out the sidewall-crash. Someone in the service dept. may be trying to kill you either intentionally or by ineptness.

..under normal load conditions - i.e. 3 or less passengers and not much in the trunk. 41 F / 41 R is for max load conditions.

I usually run 38 F / 35 R for the street - works well this way. On track, 42 F / 42 R *hot*.
