Honda S2000 (AP1), Ohlins Road & Track coilovers, G-Loc pads on stock brakes, full carbon Mugen-style hardtop (no soft top installed), sport seats/roll bar/harnesses, aftermarket exhaust, AEM V2 intake, and 225/45/17 Continental ExtremeContact Force tires on 17x9 Enkei RPF1 wheels.

Not my best work; the car has a couple more seconds in it if I could string it together, but this was literally laps 2 and 3 of the afternoon-only event and it was 109*F out, so the car and I both got a little slower after the first session :)
