After this thread I had to confirm that my pressures were in fact optimal for my settings/tires. So I used a pyrometer to check, this was the type that uses a metal probe, not a laser.
F/R
I'm running S-03s 205/225.
Camber is -1.6/-2.5
Toe is 0/ 1/4"
The Pyrometer tells me that the optimal pressure to have maximum grip at all four corners is 45/43. So if your car is set up like mine, use those pressures, then adjust from there if you want more understeer or more oversteer.
EDIT: If you have less camber than me, you need to add MORE pressure to the tires.
