Whiteline Front And Rear Sway Bar Kit, WRX, 2014+.
Category :Bushings, Mounts & Swaybar Links
Adjustable sway bars allow their stiffness to be altered by increasing or reducing the length of the lever arms. This permits the roll stiffness to be tuned for different situations without replacing the entire bar. The stiffer the bar, the more force required to move the left and right wheels relative to each other. This increases the amount of force required to make the body roll.
