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 Suspensions SB028 front and rear sway bar kit was designed by factoring in the vehicle weight, application, motion ratio, and coil spring rate. Manufactured from heavy-duty, solid 32mm bar stock (front) and solid 1-inch bar stock 9rear), the SB028 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 bars are CNC-formed for exact manufacturing tolerances and repeatable high quality. The front sway bar mounts to the car using polyurethane bushings. These bushings are molded from 88-durometer, low-deflection, polyurethane, and are internally fluted to keeps grease in the bushing. The steel sway bar mounting brackets are reinforced to minimize deflection. The rear sway bar mounts to the rear lower control arm in the factory location.
