Lowering Springs
BMR Suspension believes the right springs go beyond looks-your GM A-body needs to perform, too! All BMR springs are manufactured from chrome silicon high-tensile spring wire, and are cold wound on a CNC coiling machine. The CNC coiling head can adjust the spring diameter in real time to ensure that every spring is exactly the same. This guarantees that your right spring matches your left spring. Every BMR spring is compressed solid at the factory, not once, but twice. This gives the spring its permanent set, and guarantees no sag. BMR springs are stress-relieved at 750 degrees F, ensuring most stresses induced during the winding process are eliminated. All springs are then shot-peened to eliminate residual surface stresses. Many spring manufacturers skip this step, but BMR insists on this operation as part of our spring manufacturing process. Every spring is computer tested as the last step-every spring, not just a sample from each batch. Each spring is loaded in the spring tester at the factory, then compressed and the CNC load cell measures the force for a variety of spring lengths. This allows BMR to offer a LIFETIME WARRANTY against spring sag.
Blending aesthetics and performance, BMR has designed the for the street performance crowd who want to use their cars in a variety of application. These springs will drop the front end of your 1964-1966 GM A-body 1-inch, and feature a fine-tuned spring rate to give you great handling and a smooth ride. The linear spring rate offers plenty of support, keeping the body flat and level in the corners, while remaining soft enough for a comfortable ride on any road.
Sway Bars
Stock sway bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMR Suspension’s 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.
BMR Suspension designed the sway bar kit for street performance, autocross, and road race applications. The large sway bars’ increase in rate gives you the ability to drive to and from the road course or autocross and still out handle the competition with the same sway bars. The SB028 front and rear sway bar kit gives you a 400% (front) and 200% (rear) increase in sway bar rate. These rate increases allows you to greatly reduce the body roll of your A-body so you can drive harder through corners. The SB028 attaches to your A-body with 88-durometer polyurethane bushings (front), reducing the deflection from the stock rubber bushings. This allows for more sway bar control, and more control equals better handling.
Shocks
Ride, handling and control are what a shock absorber provides. Compromise in one area may create a problem in another. Bilstein's patented design reduces the need for compromise. The rising rate valving of the Bilstein shock absorber provides the necessary damping to react quicker to road conditions without sacrificing ride comfort. This combination of valving and high pressure nitrogen gas keeps the tires in constant contact with the road helping to ensure safety through enhanced control.
Of all a vehicle's suspension components, nothing works harder than the shock absorbers, making it critical to pick the correct ones. Bilstein Gas Pressurized Shock Absorbers are the least expensive, fastest way, to dramatically improve the ride, handling and control of a vehicle.
