Whiteline Front Lower Control Arm - 2011-2014 Subaru WRX/STI

Precision Handling for the Widebody WRX & STI
The 2011–2014 Subaru WRX and STI are some of the most capable AWD platforms ever built, but the factory front suspension geometry leaves a lot on the table. The Whiteline KTA291 Front Lower Control Arm Upgrade Kit is designed to reclaim that lost performance. By replacing the stock stamped steel arms with high-strength, lightweight aluminum alloy units, you reduce unsprung mass and allow your dampers to work more effectively.

Anti-Lift & Caster Correction Pre-Installed
The KTA291 comes pre-assembled with Whiteline’s legendary synthetic elastomer bushings, featuring built-in Anti-Lift and Caster Correction. This specialized geometry keeps the front tires pinned to the asphalt during hard acceleration and adds roughly +0.5° of static caster. This results in a more "weighted" steering feel, improved self-centering, and a dramatic increase in turn-in response that makes the car feel years younger.

• Lightweight Aluminum Alloy: Shaves significant unsprung weight compared to factory steel arms.
• Pre-Assembled Performance: Includes high-durometer synthetic elastomer bushings for a "set it and forget it" installation.
