SPL adjustable Rear Lower Camber Arms (RLL) for the GR86/BRZ/WRX allow for adjustable camber, track, and installed motion ratios while significantly reducing the unwanted dynamic alignment change and binding that occurs with rubber or polyurethane bushings. The lower arm also handles the forces transmitted through the springs, shocks, and sway bar. By increasing the strength (rigidity) of the arm and using a spherical the rear suspension will have improved response, better lateral grip, and provide clearer feedback to the driver. Adjustable Motion Ratios The three position mounting holes for the sway bar endlinks and shock mount allow you to adjust the mounting points to prevent endlink binding and quickly adjust motion ratios to change spring and sway bar effectiveness. Simply put, it's like having adjustable spring rates without a spring replacement. For example, a 6.0 kg/mm (336 lbs/in) main spring could act as a 6.8 (380 lbs/in), 6.0, or 5.2 kg/mm (294 lbs/in) spring, giving +/- 13% of adjustability. Likewise the sway bar endlink can be installed to act like a 0.5mm larger or smaller bar, so an 18mm bar would act like an 18.5mm, 18.0mm, or 17.5mm bar depending on setup (endlink geometry permitting). Unrivaled Adjustability Range The large-diameter chromoly double adjuster and 5/8" (15.8mm) rod end allows for up to 1.375" (35mm) of total length adjustment, a 50% increase compared to many other options on the market.
