Powerflex Gear Box Mount Bushing Polyurethane Bushing Inserts. This is a great addition for your MINI Cooper and Cooper S R50 R52 R53. These are a  urethane set designed for street or track use.  With the stock rubber drivetrain mounts the engine and transmisson tends to rock or jerk when starting out or shifting hard. These bushings are a great way to prevent that. The bushing replaces the rubber part of the trans mount and slides into the mount to fit perfect and lock the transmisson down.  For full race use we recommend the wmw race gearbox bushing.
