The IAG Street Engine Mounts significantly reduce engine movement from worn out OEM mounts and provide a solid feel from the drivetrain during driving. The 75A durometer bushings included with the mounts are 5-7% stiffer than the GROUP N mounts so very little NVH (Noise Vibration Harshness) is added in the cabin. The mounts feature cold rolled gold zinc plated steel brackets, 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 out the bushings, adapting to the needs of the car. Our Street Series mounts start with a 75A bushing but allow you to upgrade to 90A or Solid bushings in the future. Instead of having to purchase new stiffer mounts, you can simply purchase a bushing kit and change your mounts to Competition or Race level performance. IAG's mounts are designed to fit the EJ series engines for the 2008-14 WRX, 2005-09 Legacy GT. Important note:IAG Engine Mounts require the use of the OEM engine mounting plates found on the 2002-07 WRX, 2004-20 STI and 2004-08 Forester XT. IAG's engine mounts for the 2008-14 WRX and 2005-09 Legacy GT come with the correct OEM engine mounting plates for an easy installation.
