1) toward the end of each session I was experiencing a spongy brake pedal. I assume it was due to overheated fluid since I did have brakes but the pedal travel was longer and softer. My car has only 23k miles and fluid was flushed 3k miles ago per the dealer. Should I change to a high temp fluid like castroil?
2) I do think I should change brake pads. I looked at Akebono as a hybrid track/street pad but got a bit of sticker shock. From reading this post and others Ferodo seems to be the pad of choice. Is this a good street and track pad?
3) Tire pressure: my cold tire pressure was 33. On the track after a few laps with heated tires my pressures went up to 38-40 pounds. That seem very high to me. Should I be starting with a lower cold tire temp?

Stock pads during that event? Change those and report back after the next event prior to changing fluid.
36-41PSI hot is right based on my experience, but others here may prefer to run less. Make sure to check with an actual tire gauge if possible.
