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 Suspension?s SB760 front and rear sway bar kit was designed by factoring in the vehicle weight, application, motion ratio, coil spring rate, and adjustability requirements. Manufactured from heavy-duty 35mm (front) and 22mm (rear) DOM steel tubing, the SB760 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. Thrust washers are welded to the front bar to locate the sway bar bushing mounts. This is critical as it properly locates the sway bar and prevents lateral movement during hard cornering maneuvers The SB760 attaches to your S550 Mustang with polyurethane bushings, reducing the deflection from the stock rubber bushings. These bushings are made from low-deflection polyurethane with a 95-durometer hardness for the front and 88-durometer for the rear, and feature internal flutes to retain grease for optimal performance.
