The IAG Performance Race Series 6 Speed Transmission Mount is designed to help eliminate drivetrain movement for racing applications. The mount features our Race Series solid steel bushings that are significantly 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, flushed 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 Street Series Black 75A bushing kit or Competition Series Red 90A bushing kit. Due to the solid race bushings and construction of the mount NVH or noise vibration and harshness will be experienced in the cabin.
