20mm 3-Point Adjustable Front Sway Bar

The Whiteline Front Sway Bar, model WHLBSF45Z, is a 20mm, 3-point adjustable sway bar engineered to enhance the handling performance of the 2013-2021 Scion FR-S, Subaru BRZ, and Toyota 86 (ZN6/ZC6). This sway bar is constructed from solid spring steel and features a durable silver powder coat finish. This particular 20mm sway bar is presented as an entry-level upgrade that provides a noticeable improvement in roll stiffness over the factory bar. Whiteline emphasizes that this bar offers a softer tune, intended to reduce body roll significantly without fundamentally altering the ZN6/ZC6 platform's characteristic playful handling. The three adjustment positions allow for fine-tuning the sway bar's stiffness to suit various driving conditions, from street use to mixed applications. Compared to a more aggressive 22mm option, the 20mm WHLBSF45Z is recommended for drivers who want improved roll control while maintaining the car's natural balance and responsiveness. The manufacturer, Whiteline, has been developing suspension components since 1979 in Australia, focusing on measurable improvements in handling, stability, and tire contact through engineering and track validation. Installation is described as a straightforward swap of the OEM bar. For optimal performance, especially on lowered vehicles, the use of adjustable endlinks is recommended to ensure the sway bar operates at zero preload at the new ride height.
