Whiteline Control Arm Rear Lower Front – 2016 Ford Focus RS

Upgrade the Rear Lower Control Arm on Your Focus RS
The rear lower front control arm on the 2016 Ford Focus RS is a critical geometry link in the rear multi-link suspension. Whiteline’s replacement arm is built from high-quality materials with improved bushing geometry to reduce compliance under cornering and braking loads. With Ford’s rear differential and torque vectoring system relying on consistent rear geometry, a properly built control arm is essential for getting the most from the RS platform.

DETAILS

• High-quality construction with improved bushing geometry
• Reduces rear suspension compliance under cornering and braking
• Supports correct operation of Focus RS rear differential and torque vectoring
• Fitment: 2016 Ford Focus RS
• Direct bolt-in — no chassis modification

Why the Rear Geometry Matters So Much on the RS
The Focus RS uses a sophisticated multi-link rear suspension paired with an active torque-split rear differential. The differential system makes torque vectoring decisions based on wheel speed and lateral acceleration inputs — but those inputs are only as clean as the geometry allows. If the rear control arms are allowing excessive compliance, the differential is responding to a noisy signal. Correct-geometry control arms are part of the foundation the electronics need to work properly.

Improved Bushing Specification
Whiteline’s replacement arm uses bushing geometry optimized for the Focus RS’s suspension kinematics. The improved specification reduces the dynamic geometry changes under load that contribute to rear instability and inconsistency, giving the platform a more defined and predictable cornering balance.

Part of the Focus RS Suspension Build
The Focus RS benefits from a complete rear suspension approach — lowering springs, sway bars, endlinks, and geometry-corrected control arms. Whiteline covers all of these positions for the RS, and this arm is a natural fit alongside those upgrades.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

If you’re building your Focus RS for track use or serious street performance, the rear suspension geometry needs to be right. This control arm is one of the pieces of that puzzle.
