I just checked the manufacture part numbers for the rear shocks for this product since I was not sure as to which rear shocks to order to match the front. (There were two options on that link for rear shocks, one with MPN# 24-120395 for $104 each, and one with MPN # 24-120425, for $129 each.
Here is a link to tirerack's section for Bilstein shocks when i selected a 2010 e92 (notice the part numbers are the same)

The part numbers are not for the f30! they are for the e90 / e92 model.
Funny thing is i still don't get the difference with these rear shocks. I really want to just run bilstein shocks & H&R springs on my car, and doesn't seem like its possible here in the US. I just emailed tirerack about this about an hour ago, so hopefully hear back from them within a week, but for some reason i am doubtful they actually have them.
