Whiteline Adjustable Rear Lower Control Arm – 2008-2026 Subaru WRX / 2008-2021 STI

On-Car Camber Adjustment Across Five Generations of WRX and STI
Whiteline’s adjustable rear lower control arm covers the 2008-2026 Subaru WRX and 2008-2021 STI — spanning the GR, GV, VA, and VB WRX chassis and the GR and VA STI. This arm provides on-car rear camber adjustability that the factory suspension doesn’t offer, correcting geometry after lowering, compensating for camber added by suspension modifications, and enabling proper rear alignment on cars used for track and performance driving.

Why Rear Camber Adjustment Matters on These Platforms
The WRX and STI are popular platforms for both street builds and dedicated track cars. Any ride height change — springs, coilovers, or even spring sag over time — affects rear camber. Too much negative camber from lowering wears the inner tyre edge. Not enough and cornering grip suffers. Adjustable arms put the correct value in reach regardless of ride height.

Five Chassis Generations, One Part Number
The 2008 model year marked a significant update to WRX and STI rear suspension geometry, and Whiteline’s arm maintains consistent fitment across the GR, GV, VA, and VB platforms. This long production run coverage means the investment in these arms applies regardless of which generation you’re building.

Track Use and Alignment Stability
On a track car, rear camber drifts as suspension geometry is repeatedly cycled through its range. Adjustable arms allow you to re-set camber to the desired value after a weekend of use — maintaining the setup rather than letting geometry drift as components wear.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979.
