The IAG Competition Series Engine Mounts are designed to be a streetable mount with weekend competition in mind. These are ideal for the person that is looking for performance gains at the road course, dragstrip or autocross but still, drives their car on the street. The 90A durometer bushings included with the mounts are 30% stiffer than the Subaru GROUP N mounts so some additional NVH (Noise Vibration Harshness) is added in the cabin. The engine mounts feature cold rolled, gold zinc plated steel brackets with gold zinc plated pins, hardware, and aircraft grade 6061 billet aluminum anodized carriers that are machined in-house. Unique to IAG's Engine Mounts is the ability to change the bushings to adapt to the needs of the car. Our Competition Series mounts start with 90A bushings but allow you to change to softer 75A or a stiffer race Solid bushings in the future. Instead of having to purchase a new set of mounts if you want softer or need stiffer bushings, you can simply purchase a bushing kit and change your mounts to street or race level performance. IAG's mounts are designed to fit the Subaru EJ series engines for the 2002-07 Subaru WRX, 2004-21 STI, 2004-08 Forester XT.This Part Fits: Year Make Model Submodel Notes 2006 Subaru Forester XT Limited 2007 Subaru Forester XT Limited 2002 Subaru Impreza WRX 2003 Subaru Impreza WRX 2004 Subaru Impreza WRX 2005 Subaru Impreza WRX 2006 Subaru Impreza WRX 2007 Subaru Impreza WRX 2004 Subaru Impreza WRX STI 2005 Subaru Impreza WRX STI 2006 Subaru Impreza WRX STI 2007 Subaru Impreza WRX STI 2008 Subaru Impreza WRX STI 2009 Subaru Impreza WRX STI 2010 Subaru Impreza WRX STI 2011 Subaru Impreza WRX STI 2012 Subaru Impreza WRX STI 2013 Subaru Impreza WRX STI 2014 Subaru Impreza WRX STI 2015 Subaru WRX STI 2016 Subaru WRX STI 2017 Subaru WRX STI 2018 Subaru WRX STI 2019 Subaru WRX STI 2020 Subaru WRX STI 2021 Subaru WRX STI
