Street Series Billet Aluminum Transmission Mount

Upgrade your Subaru WRX or WRX STI’s drivetrain control with the IAG Performance Street Series 6 Speed Transmission Mount. Designed specifically for 2022-2025 WRX, 2004-2021 Subaru WRX STI, and 2007-2009 Legacy GT Spec. B models, this mount reduces drivetrain movement to improve shift timing and feel during spirited driving. Crafted from CNC-machined billet aluminum, the mount features durable Black 75A Street Series bushings that are slightly stiffer than OEM Subaru GROUP N mounts. For more aggressive drivers, bushings can be upgraded to Red 90A Competition Series (sold separately) to further reduce movement at the expense of additional noise and vibration. The flush hardware design allows for a quick 30-minute install with basic tools, and bushings can be swapped in minutes to adjust stiffness. This transmission mount offers the perfect balance of performance and comfort for enthusiasts seeking a more connected driving experience. It is ideal for Subaru enthusiasts who want improved shift precision without sacrificing daily drivability.
