Whiteline Rear Sway Bar 22mm Adjustable 2004-2007 STI

Upgrade your 2004-2007 Subaru WRX STI’s handling with the Whiteline Rear 22mm Adjustable Sway Bar. Designed to fine-tune your car’s balance, this premium sway bar lets you adjust stiffness to reduce oversteer or understeer, improving cornering precision and overall driving confidence.

Featuring a 3-hole design, the 22mm adjustable sway bar allows you to vary the effective arm length, controlling weight transfer and suspension response. You can even set each side independently—from softest to hardest—to customize handling characteristics to your driving style. Increasing rear sway bar stiffness enhances oversteer, while a softer setting reduces it, giving you precise control over your STI’s dynamics.

Ideal for Subaru enthusiasts seeking better track or street performance, this sway bar is a must-have suspension upgrade.
