Overview:

The Whiteline 18mm Adjustable Rear Sway Bar + Brace is a premium suspension upgrade designed specifically for the Scion FR-S (2013–2016), Toyota 86 (2017–2020), and Subaru BRZ (2013–2020). This adjustable sway bar enhances your vehicle’s handling by reducing body roll during cornering, resulting in improved grip, better tire wear, and a more composed driving experience. Ideal for enthusiasts seeking a balance between daily comfort and spirited driving performance, this sway bar allows you to fine-tune roll stiffness without the need to replace the entire bar.

By increasing the sway bar’s stiffness, the Whiteline 18mm Rear Sway Bar helps distribute cornering forces more evenly across the tires, keeping them flatter and more upright. This translates to greater traction and confidence through bends, making it one of the most cost-effective handling upgrades available for these popular sports cars.
