Hi,
I found an australian yokohama page recommending tire pressures of 33-36 and temperatures in the 60-90 celsius range (140-195 Fahrenheit)
.

The faster guys in bmwcca spece36 seem to think 30-32psi is the hot setup, anything higher less grippy and burning up tires (they say).
I haven't done all the experiments yet, but I was getting a pretty good pyrometer ramp at about 37psi. But my car and I aren't that set up, so we couldn't really gauge speed yet.
Does tirerack have recommendations?
