I checked the pressures the next morning when things had cooled down in the garage and about 75ºF out and the pressures read 32/33 in the front and 34.5/33.5 psi in the rear. I started the track session at 34 front and 35 rear (1 psi under the door jam pressures).
I guess next time I will run them even lower when I set them cold and make sure to keep letting air out.
Any other hints or tricks would be welcome.

Yeah, start at lower psi than 34/35.
On my R-S3, to aim for 38 psi hot (track pressure), I start out at 30 psi cold in the morning (and, monitor & bleed/add throughout the day).
