Purchased this LSD last summer with plans to install this on my 2014 435i (AUTOMATIC). Never got around to it, and Not sure I ever will, especially after shifting my focus to work on my next current project- M3. The LSD has never been installed and is brand new, as it were from the factory. Not looking to turn a huge profit by any means. Would be greatful to recover the money I spent on this mod. It’s a shame because I only heard great things about this upgrade, especially on the N55 platform. My loss = your gain.
