How did you get your weight down to 2800 sans driver? 3250ish stock Z4M, that's 450lb. I can only image that you have no AC, interior is stripped (not much of it anyway), Airbags gone, ABS gone, Passenger seat gone, no radio, etc etc?
Love the wing setup! And that car IS loud. My Z4 with straight pipe (no muffler or resonator) on the 2J sounds like a muffled jet compared to what you guys can do on normally aspirated S54s. Jealous
