Tire pressures

What kind of tire pressure are you guys running? The manual says for 18" wheels (which is what I run), recommended pressure is 36/44 lbs. That seems REALLY high, and ride at that pressure is really rough. I'm on Nitto NT-01s (drive to the track). Hot pressures at the track run about 32/36. But what about cold pressure on the street?
P.S. It's a '99 996 C2

36/44 on the street. I drop to 42 in the rear for autocross, but I have rear camber close to max at -2 degrees.
Keep in mind I bleed the pressures off between runs to keep the hot pressure the same. I have to pump them back up when I leave the event.

Remember, more pressure-> less contact patch, less rolling resistance, less rollover onto sidewall when cornering
Less pressure-> more contact patch, more rolling resistance, more rollover onto sidewall
Lowering the pressure might "soften" the effective spring rate of the tire, but you will experience more rolling resistance, more likelihood of a big hit deforming the tire enough to debead or damage the wheel, and more deformation under cornering.

right. my main focus on tire pressure is handling not ride comfort. even on the street because that one time you need to avoid a ladder that just fell off a truck is when you will need that razor sharp response from a tire that does not load up deform and then change direction of the car.

Can't find anywhere that sorts this out technically for me.
