Overview

The SuperPro ALOY0014K is a front lower alloy control arm kit designed for the 2008-2014 Subaru Impreza WRX STI. This kit features lighter and stronger alloy control arms, providing an STI-style upgrade over the stock steel arms. It incorporates proprietary polyurethane and DuroBall compound bushings to reduce deflection and enhance tire performance, leading to better traction and grip.

The kit includes anti-lift geometry, which helps maintain tire contact with the pavement during acceleration for more efficient power delivery. It also comes with all necessary hardware and new ball joint bosses, eliminating the common issue of corroded original parts making re-use difficult. This standard geometry version is recommended for vehicles with significantly lower ride heights, wider tire packages, or more aggressive wheel offsets, preventing potential tire rub at full steering lock that can occur with additional caster.
