Performance Aluminum Bushing Kit

The SMY Performance Pillow Ball CNC Aluminum Adjustable Rear Control Arm / Toe Kit offers advanced alignment capabilities compared to stock components. This updated system replaces previous steel versions with a lightweight, CNC-machined aluminum construction, providing a significant weight reduction of 2lbs per arm. The included pillow-ball ends and 80-durometer bushings are designed for increased durability and handling response. This kit is compatible with 2008-2021 Subaru WRX STI, 2008-2021 Subaru WRX, and 2022+ Subaru WRX models. The control arms provide a camber adjustment range of +12mm to -12mm, while the toe arms offer a range of +/- 3 degrees for fine-tuned suspension geometry. Each kit includes two aluminum rear control arms, two steel toe arms, necessary hardware, and SMY decals. Professional alignment is highly recommended after installation to ensure proper vehicle handling. The manufacturer specifies torque requirements for installation, including 34 ft-lbs for endlink bolts, 89 ft-lbs for control arm mounting points, 74 ft-lbs for the toe arm subframe side, and 44 ft-lbs for the toe arm end. This product is backed by a limited 10-year warranty.
