# BMR 15-17 S550 Mustang Rear Hollow 25mm 3-Hole Adj. Sway Bar Kit - Red

The two primary functions of sway bars are to control body roll and to determine the understeer or oversteer behavior of a vehicle. Stock sway bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMR's suspensions SB045 rear sway bar was designed by factoring in the vehicle weight, application, motion ratio, coil spring rate, and adjustability requirements. Manufactured from heavy-duty 25mm bar stock, the SB045 is cold formed to better resist torsional fatigue and retain its "memory" far longer than the hot-formed bars used by many competitors. The sway bar is CNC-formed for exact manufacturing tolerances and repeatable high quality. The SB045 attaches to your S550 Mustang with 88-durometer polyurethane bushings, reducing the deflection from the stock rubber bushings. These bushings are molded from 88-durometer, low-deflection, polyurethane, and are internally fluted to keep grease in the bushing.BMR's suspension designed the SB045 sway bar for street performance, autocross, and road race applications. The three-way adjustable SB045 gives you a 63%-208% increase in rate over the stock bar. The rate increases gives you improved handling characteristics so you can drive harder through corners with minimal body roll. This allows for more sway bar control, which equals better handling. When performance is a must, rely on BMR's suspension!BMR's suspensions SB045 sway bars are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is about 1-2 hours. Proudly made in the U.S.A.!
