Whiteline Front and Rear Sway Bar for E9X 335i - 27mm front, 20mm rear non-adjustable. Whiteline Sway Bars are designed for drivers who desire improved handling and lower body roll without lowering or affecting ride quality. Whiteline Sway Bars increase your suspension’s roll stiffness—or its resistance to roll in turns—while maintaining ride comfort and dramatically increasing cornering control, lateral stability, and grip. A much needed upgrade if you plan to track your car!
Note: Fits the '06-'11 BMW E9X
