Starting 40/36 COLD may not be optimal. But then again, I'm talking from road course experience so I'd imagine on a much shorter, one lap auto-x course may be different from my knowledge base.
Yup, tire pressures for road course are different from autox. I do both autox and tracks, and I always set my tire pressures accordingly. For autox, I run high pressures (45/40 f/r cold), but for track, I target 38/35 hot.
