Improve rear suspension response with the Whiteline BSR53XZ 18mm Xtreme heavy-duty adjustable sway bar, engineered to activate more grip and enhance vehicle handling. By reducing body roll during cornering, this sway bar helps distribute lateral loads more evenly across the tires, supporting greater cornering traction, sharper turn-in and improved overall performance. It is designed as a direct handling upgrade for select 2013–2015 Scion FR-S and Subaru BRZ applications, as well as compatible Toyota 86 models, without compromising ride quality or everyday comfort.
The Whiteline BSR53XZ features multi-point adjustment, allowing drivers to fine-tune rear suspension characteristics for different driving preferences, road conditions or performance requirements. Its 3-point adjustment design provides greater control over vehicle balance and handling behavior, making it suitable for street driving, spirited use and track-focused setups. The sway bar is supplied as the bar only and is engineered for strength and dependable performance at the sway bar link mounting points.
Premium anodized alloy materials provide a durable protective barrier against corrosion and wear while maintaining a clean, performance-oriented appearance. Forged ends help maximize strength where the sway bar connects to the links, while Whiteline's synthetic elastomer technology resists oil, grease, ozone and weathering for long-term durability. By helping reduce unwanted body movement, this rear sway bar can also contribute to improved handling confidence, safety and tire wear without introducing a harsh or uncomfortable ride. Professional installation is recommended, and fitment should be verified for the specific vehicle configuration before purchase.
