Whiteline Front and Rear Sway Bar Kit – 2013-2021 Scion FR-S / Subaru BRZ / Toyota 86

Complete Anti-Roll System for the ZN6/ZC6
The Whiteline BSK020 is a matched front and rear sway bar kit for the 2013-2021 Scion FR-S, Subaru BRZ, and Toyota 86. Both bars are blade-adjustable, all mount hardware is included, and the kit is engineered as a matched system for the FA20-powered ZN6/ZC6 chassis. It directly addresses the factory’s deliberately loose rear sway bar calibration while providing a balanced, tunable anti-roll system.

ZN6/ZC6 Factory Calibration and This Kit
The FA20-powered ZN6/ZC6 arrived with small-diameter sway bars — particularly at the rear — tuned for playful, adjustable handling. That calibration makes the car entertaining but limits precision and consistency at the limit. Whiteline’s BSK020 increases front and rear roll stiffness in matched proportion, delivering a more controlled and confidence-inspiring handling character.

Matched for Balance
Both front and rear bars are included, matched in diameter and stiffness for balanced roll stiffness distribution. Running only a front or rear upgrade on this platform produces an imbalance. The complete kit ensures both ends are addressed proportionally.

Adjustable for Your Setup
Blade-adjustable front and rear bars let you tune the balance for your specific driving style and use case. Track day, autocross, and street use can all be accommodated with different position settings.

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 foundational anti-roll upgrade for the ZN6/ZC6. Matched, complete, and directly targeted at the platform’s well-known factory calibration compromise. 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.
