BTW, off topic, I've read your comments on here, and other sections of the forums about driving with traction control off. For a vehicle like ours without a stock LSD, this is VERY VERY dangerous. Our car is too prone to snap oversteer. You can drive the car with dsc limited, but as others told you in those threads, it's a bad idea to turn the system off completely. I and even a very experienced instructor have done 360 degree spins in either direction with DSC off. A guy on here who I introduced to the track crashed with his 335I because he ignored this warning, that I gave him in person, at the track.
