Weak or standard OEM transmission mounts often allow drivetrain movement, leading to issues with shift timing and quality. IAG’s Street Series Transmission Mount is engineered to control drivetrain movement during high-performance driving, resulting in a more precise shift feel. Designed to fit seamlessly with 2004-2021 Subaru STI and 2007-2009 LGT Spec B models with 6 speed transmissions, this durable mount effectively suppresses excessive vibrations, making it ideal for high-powered builds and demanding driving conditions.
RUGGED CONSTRUCTION
The IAG Performance Street Series 6 Speed Transmission Mount provides secure support for your Subaru’s transmission because of its robust construction. It features our Street Series Black 75A durometer bushings, offering slightly more stiffness compared to 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 IAG Competition Series Red 90A bushing kit.
FINE-TUNE YOUR MOUNTS
The IAG Performance Street Series 6 Speed Transmission Mount comes with our Black 75A Bushings, but can be easily swapped out with our Competition Series Red 90A Bushing Kit (sold separately). The 90A durometer bushings are even stiffer than our 75A Street Series Bushings, providing an increased reduction in movement of the transmission under hard acceleration. Due to the higher durometer, additional NVH (Noise Vibration Harshness) will be noticeable throughout the vehicle’s interior.
STRAIGHTFORWARD INSTALLATION
IAG’s Street Series 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.
