SPL Parts 2013+ Subaru BRZ/Toyota 86 / 2015+ Subaru WRX/STI Rear Lower Camber Arms

With this set of SPL Parts Rear Lower Camber Arms, you get the arms themselves, designed to give you precise control over your vehicle's rear suspension alignment. These arms are built for a range of popular sports cars, including the 2013+ Subaru BRZ and Toyota 86, as well as the 2015+ Subaru WRX and STI models. They replace your stock lower control arms, which often use rubber or polyurethane bushings that can deflect and bind under load. By using high-strength spherical bearings, these SPL arms significantly reduce unwanted dynamic alignment changes and binding, leading to a more responsive and predictable rear suspension feel.

What really sets these arms apart is their adjustability. You can fine-tune your camber settings for better tire contact on the road or track. Plus, the three-position mounting holes for the sway bar endlinks and shock mount allow you to adjust motion ratios. This means you can effectively change your spring and sway bar rates without actually swapping out those components. For example, you can adjust the feel of your main spring to be about 13% stiffer or softer, or tune your sway bar to act like a thicker or thinner bar, all depending on how you set up the endlink geometry. This level of adjustability is crucial for dialing in your suspension for specific driving conditions, whether it's spirited street driving or track days. The arms themselves are constructed from lightweight, anodized black 6061-T6 aluminum, with a robust electroless nickel-plated chromoly steel double adjuster that allows for a wide range of length adjustments, giving you more tuning capability than many other options.

Beyond the adjustability, these arms are built to last and perform. They feature self-cleaning, US-made PTFE-lined FK bearings that are designed to handle the stresses of performance driving. The arms are also notably lighter than stock, weighing in at just 3.57 lbs each, which is about 17% lighter than the original equipment. This reduction in unsprung weight can contribute to improved suspension response and a clearer feedback from the road. All the hardware, including the titanium socket head screws, is included to make installation as straightforward as possible, allowing for easier, on-car adjustments without the need for jam nuts.
