E36 Billet Aluminum Euro Differential BracketDescription Some of these photos look like renderings of our CAD files, but they are actual photos. We have always been very impressed with the quality of machining on these differential brackets, but the most recent batch of parts are the best to date. 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
