Whiteline Front & Rear Anti-Roll Bar Kit – 2022-2025 Subaru WRX

Complete Front and Rear Sway Bar Package for the VB WRX
The Whiteline front and rear anti-roll bar kit for the 2022-2025 Subaru WRX pairs the BSF51Z 24mm front bar and the BSR57Z 22mm rear bar in a single purchase, with all hardware included for a complete installation. Both bars are adjustable — multiple positions allow you to tune the front-to-rear roll stiffness balance for street, track, or autocross use. This is the correct sway bar combination for the VB WRX, validated together by Whiteline for balanced performance.

DETAILS

• Front and rear sway bar kit for 2022-2025 Subaru WRX (VB chassis)
• 24mm front bar + 22mm rear bar — both adjustable
• Includes mount bushings, endlinks, and hardware for complete installation
• Both bars validated together for balanced handling improvement
• Hollow chromoly steel construction

Why Matched Front and Rear Bars
Sway bar stiffness is relative — a stiffer front bar with an unchanged rear shifts handling balance toward understeer. A matched kit ensures both ends of the car are addressed proportionally, producing a handling character that reduces overall body roll while maintaining a predictable, balanced front-to-rear relationship. Whiteline’s kit pairing is based on testing, not arbitrary diameter selection.

Adjustment Positions on Both Bars
Having adjustment positions on both front and rear bars gives you two-dimensional tuning capability. You can run both on the inner (softer) position for a street-oriented setup, or move either or both to the outer (stiffer) position as the build progresses toward track use. The ability to tune the balance separately is the key advantage over buying fixed-diameter bars.

Complete Installation Hardware
All mount bushings, brackets, and endlinks are included. This is a complete sway bar installation kit — everything you need comes in the box.

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 sway bar combination for any serious VB WRX build. Matched bars, both adjustable, complete hardware — everything you need to significantly improve the VB’s handling in one purchase. 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.
