Fits 2008-2026 Subaru Impreza WRX/STI, WRX, and BRZ, 2013-2016 Scion FR-S, and 2017-2026 Toyota 86/GR86.

SPL Parts Adjustable Rear Lower Camber Arms (RLL) provide precise control over camber, track width, and motion ratios. These arms replace soft factory rubber or polyurethane bushings with high-articulation spherical bearings to eliminate dynamic alignment changes and binding. By increasing arm rigidity, these components improve lateral grip and provide the driver with clearer tactile feedback through the rear suspension.

A standout feature is the three-position mounting system for shocks and sway bar endlinks. These adjustable mounting points allow you to prevent endlink binding and effectively change spring and sway bar rates without replacing hardware. This allows for +/- 13% adjustability in spring effectiveness, making a 6.0 kg/mm spring behave like a 5.2 to 6.8 kg/mm spring depending on the position used.
