Q&A

• Does this transmission mount fit my STI? This mount fits the 2004-2021 Subaru WRX STI, the 2022+ Subaru WRX and the 2007-2009 Subaru Legacy GT spec.B with the 6-speed manual transmission.
• What is included in the box? The box includes one IAG Competition Series 6-speed mount with Red 90A bushings and four Allen socket head mounting screws.
• How stiff is this mount? It uses Red 90A durometer polyurethane bushings that are significantly stiffer than the Subaru Group N mounts, so additional NVH will be noticeable in the cabin.
• Can I change the bushing stiffness later? Yes — the bushings can be swapped to tune the mount's stiffness, and the IAG Street Series Black 75A bushing kit is available separately.
• How difficult is installation? The mount's flush hardware design means it does not need to be taken apart to install, and removing the transmission mount takes around thirty minutes using basic hand tools and a jack with jack stands.
