Product Description

The Whiteline KTA449 is a premium front lower control arm upgrade kit built for the 2022-2025 Subaru WRX. Its design focuses on restoring proper suspension geometry through roll-center correction, helping to reduce body roll and improve handling balance - especially for lowered or performance-driven vehicles.

This control arm also brings in advanced features like bump-steer correction, anti-lift, and anti-dive geometry, which improve stability under hard acceleration, braking, and steering. With camber and caster tunability, you can fine-tune alignment for optimal grip or tire wear depending on your driving needs.

Constructed from forged aluminum, the arms are strong yet lightweight, while the use of spherical bearings and polyurethane bushings allows for precise, predictable handling. This is a solid upgrade for WRX owners seeking track-capable dynamics without sacrificing daily drivability.
