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 SB039 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-wall 29mm (front) and 32mm (rear) DOM tubing, the SB039 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 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 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. BMR Suspension designed the SB039 sway bar for street performance, autocross, and road race applications. The large adjustable sway bars three positions give you the versatility to drive to and from the road course or autocross and still out handle the competition with the same sway bar. The SB039 sway bars give you a 98%-214% increase (front) and a 25%-200% increase (rear) in sway bar rate. These rate increases and adjustability allow you to fine-tune the handling characteristics of your Camaro so you can drive harder through corners with minimal body roll. The hollow design allows for loads of strength in the lightest package possible. This means increased performance with no sacrifices. The SB039 attaches to your Camaro with 88-durometer polyurethane bushings, reducing the deflection from the stock rubber bushings. This allows for more sway bar control, and more control equals better handling. When performance is a must, rely on BMR Suspension! BMR Suspensions SB039 sway bars are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is about 3-4 hours. Proudly made in the U.S.A.! FRONT Hole 1 (Boot-Leg end of bracket) 98% stiffer than OE bar Hole 2 (Center) 146% stiffer than OE bar Hole 3 (Flat end of bracket) 214% stiffer than OE bar REAR OE SS bar (FE4) -Hole number 1 provides just over 100% increase in rate over the factory FE4 bar -Hole number 2 is 150% -Hole number 3 is 200% OE ZL1 bar (FE5) -Hole number 1 provides just over 25% increase in rate over the factory FE4 bar -Hole number 2 is 40% -Hole number 3 is 75% FITMENT NOTE: SB033 IS DESIGNED AS A DIRECT REPLACEMENT FOR FE4 REAR SUSPENSION SYSTEMS, WHERE THE SWAY BAR END LINKS ARE LOCATED OUTBOARD OF THE REAR SHOCKS. THIS INCLUDES 2012+ ZL1 AND 2013+ SS. 2010-2012 SS MAY UPGRADE TO THIS FE4 BAR IF REAR LOWER CONTROL ARMS AND REAR SWAY BAR END LINKS ARE UPGRADED TO FE4 SPEC. SB033 WILL NOT FIT ON V6 APPLICATION DUE TO INTERFERENCE WITH REAR V6 BRAKE CALIPERS.
