I use even lower pressures 2.5 (to 2.6 max) cold as my starting point, and leave it at 2.8/2.9 warm.
I leave the rear at 2.4/2.5 cold normally and when warm increase slightly 2.6/2.7 (a max of 2.9 or so for loosening the tail like Peter said) depending on how the car is handlng, I would leave it at the low end of things for the ring though.

Some wear over the edge of the marker of the front sidewall does happen (due to hairpins) but any higher pressure and I find the fronts get too squirmey and understeery, the sidewall attrition doesn't seem heavy enough to worry about - the PS2's seem quite tough!

I'm not a doctor - but I really do recommend braking later
