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 SB013 rear sway bar was designed by factoring in the vehicle weight, application, motion ratio, coil spring rate, and adjustability requirements. Manufactured from heavy-wall 22mm DOM tubing, the SB013 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 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 SB013 attaches to your G8 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 keeps grease in the bushing. The fabricated laser cut, TIG-welded steel sway bar end links are reinforced to minimize deflection. The sway bar is 3-way adjustable to tune the amount of torsional spring rate and to determine the handling characteristics (understeer/oversteer) of the vehicle..
