Reinforced Rubber Transmission Mount Bushing

The STI transmission mount is a competition-spec component engineered for Subaru vehicles equipped with 6-speed transmissions. By utilizing reinforced rubber with an increased hardness rating (under 80Hs), this mount effectively minimizes drivetrain play, resulting in a more direct and connected shifting experience. This mount serves as a direct-fit performance upgrade, balancing enhanced durability with the demands of competition driving. It is compatible with a wide range of Subaru platforms, including Impreza WRX/STI (GD, GG, GR, GH, GV chassis) and Forester (SG chassis) models. Enthusiasts often pair this mount with other drivetrain upgrades like pitch stops or shift bushings for a more cohesive and engaging feel. Installation of this performance component is generally straightforward; however, users may notice a slight increase in Noise, Vibration, and Harshness (NVH) due to the stiffer durometer of the competition-grade rubber compared to factory-installed parts. Ensure proper identification of your specific vehicle chassis before installation to confirm compatibility.
