Just put the performance suspension on my 2011 335is E92 and have the stock stuff for sale. Parts have 11K miles on them, I have the full setup....springs, struts/shocks, bump stops, spring perches, and front and rear sway bars. It would be everything needed to do a sport suspension upgrade. I'll send you an e-mail.
