Made from a very lightweight tubular chromoly steel and then zinc plated. Anodized CNC aluminum brackets mount the bar to the car and include urethane bushings and a grease fitting to keep the squeaks away. The key feature of the bar set is the adjustment. Anodized CNC brackets slide on the adjustment range and clamp down when in position, allowing infinite adjustment of the bar stiffness. The bars also come with adjustable endlinks front and rear, and weigh in at a light 6 pounds for the whole front package including brackets and mounts.
