Product Description

The Whiteline BBR11Z Rear Sway Bar is a performance suspension upgrade designed for BMW 3 Series E46 models. Featuring a heavy-duty 20 mm solid spring steel construction and a two-position adjustable blade design, this sway bar reduces body roll during cornering while improving overall chassis balance. By distributing lateral loads more evenly across the tires, the bar increases cornering grip and improves vehicle stability during aggressive driving.

The BBR11Z maintains everyday ride comfort while enhancing steering response and driver confidence. The kit includes mounting hardware, links, and polyurethane bushings designed to minimize flex and ensure reliable long-term performance on the E46 chassis.
