Hardened Rubber Engine Mount

The STI Group N transmission mount provides a robust solution for drivers seeking to enhance drivetrain response and reduce excessive movement during aggressive driving. Constructed from a stiffer, higher-grade rubber compound than standard OEM mounts, this component effectively minimizes transmission flex under load, leading to improved power delivery and a more direct shift feel. Built to withstand the demands of both daily driving and track usage, this mount is a direct-fit replacement for specified models. It fits 5-speed WRX models from 2002-2014 and 6-speed models from 2015-2021. Please be aware that the increased stiffness of the Group N rubber compound can lead to a noticeable increase in NVH (noise, vibration, and harshness) compared to the factory equipment. This mount is intended for manual transmission applications. Users should verify specific fitment requirements for their drivetrain configuration before installation.
