Description

By utilizing a significantly firmer hardened rubber compound compared to standard factory mounts, this component restricts excessive engine movement, which in turn improves throttle response and provides a more precise shift feeling during aggressive driving. Please note that installing this hardened mount will result in a noticeable increase in vibration and noise transmitted into the vehicle body, which is a common characteristic of high-performance group N style components. This mount is compatible with various Subaru platforms, including the Impreza (GD/GG), Legacy B4 (BL), and Legacy Touring Wagon/Outback (BP) models. As this is a performance upgrade, it is recommended for vehicles used primarily for track or competition applications where structural rigidity is prioritized.

MIA's Description

It utilizes hardened rubber to effectively reduce power unit vibrations while providing a more direct connection between the engine and the chassis.
