If you do decide to throw a rear bar in there TMS(Turner Motor Sports) has a kit that has all of the mounts, nuts and bolts, and end-links for the install. It is all OE BMW stuff too. That is what I did when I put mine in.

*** i didn't realize someone already mentioned the Turner Kit. Another note I had to run a tap though the knuckle where the end link goes in. My car has not seen the snow but after 5 years of water the threads got a little buggered up. I don't remember the size, but I pulled the rear toe link and tapped it from the rear side of the knuckle. It was a straight shot from there.
