Whiteline Rear Sway Bar 22mm Adjustable – 2003-2008 Subaru Forester

Add Rear Roll Stiffness to Your SG Forester
The 2003-2008 Subaru Forester (SG chassis) is a tall-bodied all-wheel-drive SUV with a high center of gravity — which makes rear sway bar calibration particularly important for handling balance. Whiteline’s 22mm adjustable rear bar adds meaningful rear roll stiffness over the OEM spec, reducing body roll and improving the Forester’s cornering composure without fundamentally changing its character.

High Center of Gravity — Why Rear Bar Matters
The SG Forester sits taller than the equivalent Impreza or Legacy on the same platform. That height means more body roll per unit of cornering force, and the factory rear bar is calibrated for ride quality rather than performance. Adding a stiffer rear bar is one of the most effective ways to address the Forester’s tendency to roll significantly in corners while maintaining its ground clearance and ride characteristics.

Three-Position Adjustment
The three positions give you flexibility to match the rear bar stiffness to your front setup and driving style. A modest increase in the softest position is appropriate for a daily-driven Forester on varied terrain. The firmer positions suit a more performance-oriented build with lowering springs and front bar upgrades.

Complement With Front Bar and Endlinks
Whiteline offers a front sway bar for the SG Forester as well. For the most balanced improvement, pair front and rear bar upgrades. The SG Forester responds well to a complete anti-roll upgrade — the reduction in body roll that results makes the car feel significantly more composed and predictable.

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

A well-chosen upgrade for SG Forester owners who want better handling without compromising ride quality or versatility. The adjustability keeps it practical across different use cases. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
