Product Description

The Whiteline BSR37XZ is a 24mm X Heavy Duty Blade Adjustable rear sway bar for the 2003-2007 Subaru Impreza WRX STI (GD Sedan and GH Hatchback). At 24mm it is larger than the OEM rear bar, providing increased roll stiffness to spread lateral cornering loads more evenly across the rear tires -- reducing body roll, increasing cornering grip, and improving rear tire wear in aggressive driving.

The X Heavy Duty Blade design allows adjustment between three stiffness settings by changing the blade arm length -- soft, medium, and firm -- without removing or replacing the bar. This lets the driver tune the rear suspension balance to suit road conditions or driving preference. Whiteline's synthetic elastomer bushings feature internal bore knurling and grease retention lips for long-service lubrication without the harshness of polyurethane. Solid steel construction throughout -- no hollow core. Made in Australia. Backed by Whiteline's 3-year limited warranty.
