Whiteline Front and Rear 22mm Sway Bar Kit – 2004-2007 Subaru STI

Matched 22mm Anti-Roll Package for the GD STI
The Whiteline BSK010 is a matched 22mm front and rear sway bar kit for the 2004-2007 Subaru STI (GD chassis). Both bars are blade-adjustable at 22mm, and all mount hardware is included. A balanced 22mm upgrade at both ends for the street and mixed-use GD STI — significant improvement without the extreme stiffness of track-only specifications.

DETAILS

• Matched 22mm front and rear adjustable sway bars
• All mount bushings and hardware included
• Fitment: 2004-2007 Subaru STI (GD chassis)
• Street and mixed-use calibration
• Direct bolt-on installation

Matched 22mm Front and Rear
Running the same 22mm diameter at both ends of the GD STI provides a balanced roll stiffness increase — neither end significantly stiffer than the other. This maintains the car’s natural handling balance while reducing body roll across both axles simultaneously.

Street-Appropriate Specification
The BSK010 is calibrated for street and mixed-use GD STI builds. 22mm is stiff enough to make a real difference in handling while remaining comfortable on normal roads and appropriately forgiving for daily use.

Adjustable for Fine-Tuning
Both bars offer three adjustment positions. Start balanced at middle positions; adjust to fine-tune the balance for your specific driving style and use case.

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 correct matched 22mm street-use anti-roll kit for the GD STI. Everything fits together as a system — the bar diameters, bushing specs, and mount hardware are all matched. Stock-height endlinks are included; if the car has been lowered, adjustable endlinks are the correct follow-on purchase. Run both bars at their middle positions first and adjust from there based on how the car responds on your road or circuit of choice.
