When replacing the boots on your rear halfshafts, you can buy a nice kit which has the boot, clamps, plate & grease to do the job effectively. Lobro manufactures the halfshafts for BMW and the Lobro boot kits are the ones that you should use. Many of my parts suppliers have been sending Febi or CRP packaged kits which are inexpensive but very poor in terms of quality & contents. If your parts house does not have the Lobro brand kits, I'd recommend spending the extra money and picking up the original kit through the dealer. SD
