Subaru Performance Alloy Control Arm Kit 07-24

The Subaru Performance Alloy Control Arm Kit 07-24 from Whiteline Performance is engineered for Subaru owners who demand precision handling and reduced suspension wear. Control arms are critical chassis components that manage wheel alignment and suspension geometry as your vehicle compresses and extends over road imperfections. Factory control arms in modern Subarus accumulate compliance in their bushings over time, introducing unwanted play that degrades steering response and increases tire wear. This performance upgrade directly addresses that issue, making it essential for daily drivers seeking improved feedback and longevity, as well as enthusiasts building platform-specific setups.

Whiteline's alloy construction replaces factory stamped steel with lightweight, rigid material that maintains precise geometry under sustained cornering and braking loads. Alloy arms reduce unsprung mass, allowing suspension to react faster to input while maintaining consistent caster and camber angles throughout the suspension travel range. The kit's optimized bushing compounds and reinforced pickup points eliminate the deflection that causes alignment drift—a common culprit in high-mileage Subarus. By minimizing compliance at the steering knuckle interface, these arms improve turn-in sharpness, reduce understeer characteristics, and extend tire life by maintaining uniform contact patch pressure across drive cycles.

This kit fits 2007–2024 Subaru models, covering popular platforms including WRX, STI, Impreza, Legacy, and Outback generations. Installation pairs well with coilover upgrades, stiffer bushings, and alignment work—the combination maximizes handling response on track or canyon driving. Mechanics frequently recommend control arm replacement during comprehensive suspension service, especially on vehicles over 80,000 miles where factory bushings have fatigued. The 17.6 lb kit simplifies ordering by bundling both driver and passenger sides, eliminating the need for multiple part searches and ensuring consistent performance across both wheel hubs.
