Description Reviews The Craven Speed Aluminum Shifter Bushings for all Gen 1 and Gen 2 MINIs are designed with 6061 aluminum to bring you a crisper, more controlled shift compared to the factory MINI shifter housing bushings. These are the same aluminum bushings that are already included with the Craven Speed Gen 1 and Gen 2 MINI short shifters, but it is not necessary to have our short shifter to install them! They will work perfectly with the factory shifter assembly. These aluminum shifter housing bushings are installed between the transmission shifter housing inside the cabin and the exhaust tunnel. These are a fitment for manual transmission MINI's only and will fit the following chassis codes : R50, R52, R53, R55, R56, R57, R58, R59, R60, and R61. They will NOT fit the Gen 3 F-cars. Kit includes, (4) aluminum bushings and four (4) replacement bolts.
