The IAG Performance Street Series 6 Speed Transmission Mount is designed to help reduce drivetrain movement during performance driving scenarios. The mount features our Street Series Black 75A durometer bushings that are slightly stiffer than the Subaru GROUP N mounts and the body of the mount is made from CNC’d solid billet aluminum. The IAG mount also features a unique flush hardware design that eliminates the need to take the mount apart to install it on the vehicle. Additionally, the IAG mounts stiffness can be “tuned” by purchasing the IAG Competition Series Red 90A bushing kit.
