To my knowledge, this is the fastest lap time in an unmodified Honda S2000.
This was my first and only time to ever run racing compound tires at a road course event. I usually run street tires.
My driving style involves staying near the upper end of the traction limit curve from the earliest moment of turn in all the way through the exit. This is hard on the tires but when going for the fastest possible time I believe this is the easiest way to navigate the track. It is easier for me to feel the feedback from the car when driving the upper limit of the traction curve. I feel that trying to drive the lower end of the optimal traction curve, or trying to stay on top of it, more often than not results in under-utilization of the available traction.

I would pit mid-session once the car started to push and lower my pressures to 37 front, 35 rear. I started at 28.5psi cold.
I used Carbotech xp10/xp12 combo and Super Blue racing brake fluid. I experienced some fade still. I also replaced my rotors with new OEM rotors. The front left rotor cracked all the way through on the last session.
It was 50 degrees outside, average humidity 29, wind speed about 14mph NNW.
Ran without my spare tire or jack. My fast lap was done on 1/2 a tank of gas. And I weigh about 190lbs.
My oil was 10w-30 synthetic. The car had 32000 miles on it. The air filter was changed 2 months prior with a stock filter.
