Reduce body roll and improve the handling of your S550 and S650 Mustang with a Sway Bar Kit from BMR's suspension! Stock sway bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMRs Sway Bar Kit (SB760) increases sway bar rate and is designed for street performance, autocross, and road racing applications. When performance is a must, rely on BMR's suspension!
