Whiteline Front Sway Bar 22mm Adjustable – 2002-2007 Subaru WRX / 2007 STI

Street and Mixed-Use Front Bar for the GD WRX
The Whiteline BSF33Z is the 22mm 3-point adjustable front sway bar for the 2002-2007 Subaru WRX and 2007 STI (GD chassis). This is the correct street and mixed-use front bar for the GD WRX — meaningful roll stiffness improvement with three adjustment positions to suit everything from a daily-driven WRX to a build that sees occasional track days.

DETAILS

• 22mm 3-point blade adjustable front sway bar
• Solid spring steel, silver powder coat
• Includes mount bushings and hardware
• 3 adjustment positions
• Fitment: 2002-2007 Subaru WRX and 2007 STI (GD chassis)
• Direct bolt-on installation

The Right Spec for Most GD WRX Builds
The BSF33Z is the most broadly applicable front bar for the GD WRX. 22mm provides a real improvement over the factory bar — reduced body roll, sharper turn-in, better front tire loading — without being so stiff that daily driving becomes uncomfortable. Three positions allow tuning for different use cases.

Three-Position Adjustment
Softer inner position for daily driving with occasional spirited use. Middle for a balanced street and track tune. Outer for more aggressive front roll control when matching a stiffer rear bar setup.

Part of the GD WRX Package
The BSF33Z pairs naturally with Whiteline’s GD WRX rear bar (BSR36Z 22mm or BSR36XZ 24mm) and the front and rear Essentials bushing kits for a comprehensive suspension improvement.

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

The standard front bar recommendation for the GD WRX. Correct spec, three positions, direct fitment. 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.
