Product Description

The SuperPro ALOY0015K Alloy Front Lower Control Arm Kit is a performance suspension upgrade designed for Subaru WRX and WRX STI platforms. These lightweight alloy arms replace the factory steel control arms while incorporating high-performance SuperPro bushings and a caster-increasing DuroBall rear bushing assembly. The result is improved steering precision, increased front-end stability, and more effective tire contact during aggressive driving conditions.

Compared to the original equipment arms, the SuperPro alloy construction reduces unsprung weight while increasing strength and rigidity. The integrated anti-lift geometry and approximately 1.5 degrees of additional caster help improve traction during acceleration and braking while sharpening turn-in response during cornering. This kit installs as a direct bolt-on upgrade and is suitable for both daily-driven and track-prepared WRX and WRX STI vehicles. Fitment confirmed through 2014 for the listed Impreza WRX platforms; compatibility beyond these years may require additional component changes depending on chassis configuration.
