Beez,

The predominant opinions on this board afor PS2's for Track/DE's seems to be running the tires @ 38-40 Hot. As aspinkus commented above AX seems to be a diferent animal. THe pressures you cited (F32-34; R 36-37) is where I usually run my PS2's on the street (34F-36R on 19"). For AX I have been running a little higher pressures but one of my instructors (non - Porsche) thinks the pressures should be running more in the range you cited "hot". I haven't felt the grip go away but it's only getting warm in Reno now. For AX is the F34 - R37 a good HOT target?
