Product Description

The **Cusco 660 911 SET Engine & Transmission Mount Set** is engineered to replace the factory engine and transmission mounts in Subaru WRX and WRX STI models spanning **2002-2021**, offering a significant upgrade in drivetrain control and responsiveness over OE mounts. Utilizing a durable high-density rubber (HD Rubber) compound bonded to robust steel mounting plates, this set limits unwanted engine movement and reduces torque steer and driveline lash during aggressive acceleration and deceleration - making power delivery feel more direct and predictable.

Designed for direct OE replacement, the Cusco mount set includes two engine mounts and one transmission mount. These mounts are a popular choice for enthusiasts who engage in spirited street driving, performance upgrades, or track events, as they help improve overall throttle response and reduce vibration compared to softer factory mounts. Installation is straightforward and bolt-on, using factory mounting points and hardware. While improved control and responsiveness are benefits, owners should expect a slight increase in NVH (noise/vibration/harshness) because of the stiffer rubber formulation - a common tradeoff for enhanced performance.
