IAG 6-Speed Transmission Mount 2004-2021 STI

The IAG Performance 6-speed transmission mount is designed to help reduce drivetrain movement during performance driving scenarios.

The Street Series mount features IAG's black 75A durometer bushings that are slightly stiffer than the Subaru Group N mounts. The body of the mount is made from CNC’d solid billet aluminum. 

Competition Series mounts move up to harder red 90A durometer bushings.

Race Series mounts use SOLID STEEL bushings. Your transmission will be hard-mounted to the body of the car. Beware! This results in high levels of vibration being transmitted into the car, and may result in chassis damage and/or shortened drivetrain component life.

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.

Fits all 2004-2021 Subaru Impreza WRX STI and 2007-2009 Legacy Spec B.
