BTW, I weighed my 09 E90 Sedan on corner balance scales at the track this weekend. Driverless, with a full tank and a 25lb baby seat it was 3722lbs. Cross weight was 53.3% and with me in the car that dropped 0.3%. I have all options except extended leather and a sunroof. That is more than I was hoping for, but it did well enough on the track with stock pads and tires that I am not too worried. It is easily faster and more rewarding to drive than a stock E46 around a 3 mile course.
Thanks for the info for the e90....
