Weak or standard OEM transmission mounts often allow drivetrain movement, leading to issues with shift timing and quality. This problem is particularly evident in racing conditions, where the drivetrain is subjected to intense vibration. IAG’s Race Series Solid 6 Speed Transmission Mount is engineered to control drivetrain movement during high-performance driving, resulting in a more precise shift feel. Designed to fit seamlessly on the 2022+ Subaru WRX, 2004-21 STI, and 2007-09 Legacy GT spec.B with 6 speed transmission, this durable mount effectively suppresses excessive vibrations, making it ideal for high-powered builds and serious racing applications.

The IAG Race Series Solid 6 Speed Transmission Mount provides secure support for your Subaru’s transmission because of its robust construction. It features our Race Series Solid Steel Bushings that are significantly stiffer than the Subaru GROUP N mounts. The mount’s body is precision-crafted from CNC-machined solid billet aluminum. Additionally, the IAG mounts stiffness can be fine-tuned by purchasing the Comfort Series 55A Bushing Kit, the Street Series 75A Black Bushing Kit and/or our Competition Series Red 90A Bushing Kit.

A standout feature of IAG’s Transmission Mounts is their interchangeable design, letting you adjust the bushing stiffness as your performance needs evolve. While the 55A durometer bushings will provide you with a quiet, comfortable ride, we also have stiffer options for high-performance applications. The next step up is our 75A Street Series Bushing Kit, Competition Series Red 90A Bushing Kit, and finally, the included Solid Steel Race Bushings that significantly increase the stiffness and NVH over the stock and GROUP N mount (Comfort, Street and Competition Bushings sold separately).

IAG’s Race Series Solid 6 Speed Transmission Mount features a unique flush hardware design that eliminates the need to take the mount apart to install it on the vehicle. The installation process is straightforward, taking around thirty minutes to complete using basic hand-tools and a jack with jack stands. Swapping out bushings can be done at the same time, adding only a couple minutes more to the task.
