So are the "i-sport springs" the sport package springs off a rwd e90 or e92?
I thought all (rwd and awd) e92's came with the sport pkg suspension while the e90's only got it with sport pkg and rwd.
Good to hear you like it, as I plan to do the same thing. Already have e90 sport pkg springs, just need the Bilsteins.
