Rally Road - E36 Billet Aluminum Euro Differential Bracket (RREBAEDB)BMW no longer sells the Euro Differential rear bracket here in the U. S. A. so we created our own version of this bracket. The Rally Road version is machined from a 1. 5" thick plate of 6061 T6 Aluminum. This bracket is much stronger than the factory cast part. It also eliminates the need to add solid bushings to the OEM bracket.
