This B&M Precision SportShifter was specifically designed for the mighty Porsche 911's, Boxsters, and Cayman models to shorten the throw by up to 35% over the factory shifter, and cleans up the inherent sloppiness found in most cable operated shifters. Constructed from 303 Stainless steel, CNC machined billet 6061-T6 aluminum and includes all necessary bushings, washers and hardware for installation. Install and enjoy the shifting performance your Porsche deserves.
