Product Description

The Whiteline BSR53XZ is an 18mm 3-point adjustable rear sway bar engineered for the Gen 1 Scion FR-S (2013-2016), Subaru BRZ (2013-2020), and Toyota 86/GT86 (2013-2021), as well as the Gen 2 Subaru BRZ (2022-2026) and Toyota GR86 (2022-2026). The factory rear sway bar on these platforms is undersized relative to the car's handling potential, allowing excessive body roll under cornering that reduces rear lateral grip and driver confidence. The BSR53XZ addresses this directly with a solid spring steel bar that is up to 98.9% stiffer than OE at its hardest setting.

The 3-point adjustment system provides three distinct effective bar diameters - 17mm (soft), 18mm (medium), and 19mm (hard) - giving drivers the flexibility to tune rear roll stiffness without removing the bar. The softer setting maintains everyday ride comfort, while the medium and hard settings progressively reduce oversteer tendency and sharpen turn-in response for spirited driving or track use. Forged blade ends, synthetic elastomer mount bushings, and included lateral locks complete the package for a straightforward, no-fabrication installation.
