Whiteline 14+ Subaru Impreza WRX (MY15) Rear Crossmember Mount Bushing Kit

If you're pushing your 2015-2024 Subaru WRX hard, especially with grippier tires, you might notice some flex or 'lateral walking' in the rear subframe during hard cornering. The factory rubber bushings allow for a good amount of movement to keep things comfortable, but that compliance can hurt performance when you're looking for precise handling.

This Whiteline kit replaces those stock rubber bushings with low-compliance polymer units. They lock the rear crossmember in place, significantly reducing that unwanted movement. The design includes soft stand-off buffers on the top and bottom, which help cushion against minor bumps and prevent a harsh, rock-solid feel, while still providing solid location when you apply torque and power. The metal components are protected with a tough plating that resists corrosion, and the synthetic elastomer formulation stands up to oil, grease, ozone, and weathering. Internal grease reservoirs and the included molybdenum disulfide grease ensure continuous lubrication for extended life.

This kit is designed to be a direct replacement for your factory bushings, helping to improve your WRX's rear-end stability and steering response when you need it most.
