Overview:

The Whiteline 16mm Adjustable Rear Sway Bar 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 driving comfort and spirited performance, this sway bar allows you to fine-tune your suspension setup without the need for multiple parts.

By increasing the roll stiffness at the rear axle, the Whiteline sway bar helps distribute cornering forces more evenly across all tires, keeping them flatter and more upright. This translates to enhanced traction, sharper turn-in, and greater overall vehicle stability.

Key Features:

The Whiteline 16mm Adjustable Rear Sway Bar offers a range of benefits and advanced features that make it a standout upgrade for your sports coupe:

• Adjustable lever arms allow for tuning of roll stiffness to suit different driving conditions and preferences
• Constructed from high-grade spring steel for superior strength and durability
• Powder-coated finish provides corrosion resistance and long-lasting appearance
• Includes high-performance polyurethane mounting bushes for improved suspension response and reduced deflection
• Reduces body roll by increasing the force required to move the left and right wheels independently
• Improves tire contact patch during cornering, enhancing grip and tire life
• DIY-friendly bolt-on installation with all necessary hardware included
• Compatible with factory suspension components, requiring no additional modifications

Construction & Design:

Whiteline’s 16mm rear sway bar is engineered from premium spring steel, ensuring optimal strength and resilience under demanding driving conditions. The bar is precision-formed and powder-coated to resist corrosion and wear, maintaining performance and aesthetics over time. The adjustable lever arms provide a versatile tuning solution, allowing drivers to modify the sway bar’s effective stiffness by changing the leverage ratio without replacing the entire assembly.

High-quality polyurethane bushes replace the factory rubber mounts, offering improved durability and reduced compliance. This upgrade enhances suspension feedback and responsiveness while maintaining ride comfort.

Performance & Sound

While the primary focus of the Whiteline adjustable rear sway bar is on handling performance, its installation contributes to a more stable and predictable chassis during aggressive cornering. By minimizing body roll, the sway bar helps maintain consistent tire contact with the road surface, resulting in improved grip and control. This translates to more confidence-inspiring handling without compromising ride quality. The sway bar itself does not affect engine or exhaust sound.

Installation & Fitment:

The Whiteline 16mm Adjustable Rear Sway Bar is designed as a direct bolt-on replacement for the factory rear sway bar on the Scion FR-S (2013–2016), Toyota 86 (2017–2020), and Subaru BRZ (2013–2020). Installation requires no cutting, welding, or permanent modifications, making it suitable for DIY enthusiasts with basic mechanical skills. The kit includes all necessary hardware and polyurethane mounting bushes to ensure a secure and precise fit.

Adjusting the sway bar stiffness is straightforward: by repositioning the lever arms, you can increase or decrease roll resistance to tailor handling characteristics to your driving style or track conditions.
