The IAG Performance Street Series 6-Speed Transmission Mount has been designed to help reduce the drivetrain movement during high-performance driving conditions. The mount features Street-Series black 75A durometer bushings that are slightly stiffer than the Subaru GROUP N mounts, and the body of the mount features CNC machined solid billet aluminum construction. This transmission mount also features a unique flush hardware design that helps eliminate the need to take the mount apart to install it on the vehicle. The stiffness can also be increased by purchasing the IAG Performance Competition Series Red 90A bushing kit (sold separately).
