Description

The Cusco Engine and Transmission Mount Set for the 2002-2005 WRX, 2004-2005 STI, and 2015-2021 STI. These strengthened mounts replace the factory engine and transmission mounts to reduce unwanted drivetrain movement and improve stability. While the factory rubber mounts work fine when new, they soften and wear over time and mileage — and under high-performance driving, the excessive engine and transmission movement causes harsh, jarring responses. This complete 3-piece kit is a direct bolt-on replacement for the factory mounts: ideal for higher-horsepower builds, aggressive suspension setups, or refreshing worn factory mounts.

  • Strengthened engine and transmission mounts with hard rubber inserts
  • Durable steel construction, powder-coated for corrosion resistance
  • Direct bolt-on replacement for the factory mounts
  • 3-piece set: 2 engine mounts + 1 transmission mount
  • Includes 2 metal washers for extra cross member clearance on some models
  • Part number: 660 911 SET

Note: The firmer construction causes a slight increase in NVH (noise, vibration, harshness) compared to the factory mounts.
