OEM Spring Rates For Various F30's?

Does anyone know what the OEM spring rates are for any of the F30s? I'm sure the rates vary depending upon whether you have a 328 v. 335 and whether you have sport line (or M-Performanc) v. luxury...etc. This information would be helpful on a variety of fronts, including for those interested in aftermarket springs or coilover set ups who want to compare them to the oem springs rates.

JMK007- Did you find out yet? I've been searching for the spring rate on the 2013 f30 335i m sport suspension. I agree, this is important information to know before changing out anything.

Thanks, I've still been looking. I found E90 specs, but going by the aftermarket specs, it's stiffer than F30's.

If I read correctly the BC coilovers for the F30 is 6kg front, 12kg rear. It seems really soft for the front and stiff for the rear.
