The Street Series Engine Mount Bushing Kit is designed specifically for IAG Subaru EJ Engine Mounts. IAG’s engine mounts feature the ability to swap bushings for street or track use. The Street Series kit includes (x8) 75A durometer bushings that are slightly stiffer than the Subaru Group N mounts. The 75A durometer bushings reduce the motor movement under hard acceleration. Due to the higher durometer used in the street series bushings, slight NVH (Noise Vibration Harshness) is perceivable through the interior.

The Competition Series Engine Mount Bushing Kit is designed specifically for IAG Subaru EJ engine mounts. IAG’s engine mounts feature the ability to swap bushings for street or track use. The Competition Series kit includes (x8) 90A durometer bushings that are stiffer than our 75A Street Series Bushings. The 90A durometer bushings help to greatly reduce the forward and backward movement of the transmission and engine under hard acceleration. Due to the higher durometer, additional NVH (Noise Vibration Harshness) is perceivable through the interior.

____________________________________________________________The Race Series Engine Mount Bushing Kit is designed specifically for IAG Subaru EJ engine mounts. IAG’s engine mounts feature the ability to swap bushings for street or track use. The Race Series kit includes (x4 2 piece) solid steel bushings that are gold zinc plated for oxidation resistance. The solid metal bushings attempt to completely reduce the forward and backward movement of the transmission and engine under hard acceleration. Due to the bushings design and material additional NVH (Noise Vibration Harshness) is perceivable through the interior.
