Cusco Sway 23mm Rear CT9A EVO7/8/9

Cusco is well-known for making performance suspension parts, and this 23mm rear sway bar is a solid example of their work for the 2003-2006 Mitsubishi Lancer. If you're looking to dial in your car's handling, especially if you're pushing it a bit harder on the street or track, a larger rear sway bar like this one can make a notable difference. It works by connecting the left and right sides of your suspension, helping to resist the body's tendency to lean into turns.

This particular bar is 23mm thick, which is a good step up from stock for many Lancers, offering a noticeable reduction in body roll without making the ride overly stiff. It's designed to fit your Lancer directly, meaning it bolts up to the factory mounting points. By stiffening the rear suspension's roll resistance, it helps keep the car flatter through corners, which can lead to improved grip and a more connected feel to the road. You'll likely notice a more balanced feel, especially when transitioning from one turn to the next.
