Product Description

The SuperPro ALOY0016K is a Supaloy front lower alloy control arm kit with standard caster geometry for the 2015-2021 Subaru WRX and WRX STI (VA chassis). This kit delivers multiple significant upgrades in a single bolt-on package. First, the alloy control arms are both lighter and stronger than the steel arms used on WRX models -- effectively providing an STI-style alloy arm set that is 38% lighter than OEM steel, reducing unsprung weight for improved responsiveness, agility, and suspension compliance. Second, the anti-lift geometry keeps more of the tire's contact patch on the pavement under acceleration, allowing power to more efficiently get to the ground.

Third, the pre-installed SuperPro proprietary polyurethane forward bushing and DuroBall compound rear bushing provide a massive upgrade over the soft, heavily voided OEM rubber bushings -- reducing deflection and movement for more consistent tire performance, better traction, improved grip, and reduced wheel hop. The smaller inner rear bushing features a bonded steel shell to minimize friction during suspension travel, allowing your springs and dampers to deliver their intended performance characteristics without interference. The corrosion-resistant alloy construction ensures long-term durability in all climates and driving conditions. Wheel alignment required after installation. Designed, engineered, and manufactured in Brisbane, Australia by SuperPro. Backed by SuperPro's 3-year warranty covering off-road, track, and competition use.
