• Front and rear endlinks included
• All mount bushings and hardware included
• Fitment: 2015-2021 Subaru STI (VA chassis)
• Direct bolt-on installation

VA STI Factory Baseline
The VA STI already has stiffer factory anti-roll hardware than the WRX — larger bars, stiffer bushings, and a performance-oriented calibration. Whiteline’s BSK019 builds further on that foundation, providing additional roll stiffness for track use and performance street driving where the factory calibration still leaves improvement available.

Complete Kit for Clean Installation
Front bar, rear bar, front endlinks, rear endlinks, all mount hardware. Everything for a complete anti-roll installation in one package. The endlinks are sized for the VA STI’s stock ride height.

Adjustable Balance
Both bars offer three blade-adjustable positions. Start at matched middle positions for a balanced improvement; fine-tune from there based on use case and driving feedback.

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 most complete anti-roll kit for the VA STI. Matched, comprehensive, and built specifically for the platform. 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.
