BMR: 1964 GM A-Body Handling performance package (Level 2)

BMR Suspension has taken the guesswork out of making significant handling improvements to the 1964 GM A-Body, and put it in one convenient package. Countless hours of design, engineering, and track testing gives you the best combination of parts for improved handling on the street and track. Matching specific components provides a great blend of performance, aesthetics, and comfort.

BMR’s Level 2 Handling Package (HPP014) addresses key points of the suspension to improve the “system.” BMR Suspension designed the HPP014 to work well for street performance and handling applications. BMR’s Level 2 Handling Package is 100-percent bolt-in and require zero cutting, welding, or modification to the chassis or suspension. Whether you simply want a better handling daily driver, or the ultimate track day car, rely on BMR Suspension!

Lowering Springs (SP032)
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 SP032 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 (SB028)
Stock sway bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMR Suspension’s 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.

BMR Suspension designed the SB028 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 (BSN-A-64-67)
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.

Front A-arms (AA033)
A-arms are one of the most important, yet overlooked suspension components. They are the direct link between the front wheels and the chassis. Any deflection causes a change in alignment, which results in poor performance and driving feel. Fabricated from heavy-duty 1.25-inch, 0.095-inch wall DOM tubing with laser-cut, CNC-formed plate steel braces for extra strength, deflection is eliminated with A-arms from BMR Suspension. BMR’s AA033 Upper and Lower A-arms are equipped with CNC machined, nickel-plated, dual-offset cross-shafts with heavy-duty stainless bushing retainers. They come pre-assembled with new polyurethane bump stops, and new upper ball joints are included. Greasable, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMR’s bushings are internally fluted, which allows grease to evenly coat the inner sleeve. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings.

BMR’s AA033 Upper and Lower A-arms eliminate A-arm deflection, greatly improving steering feel and response in normal and performance driving situations. The compact design provides additional header clearance over stock A-arms, allowing you to run larger primary tubes for high-horsepower applications. The polyurethane bushings add strength and reduce deflection over the stock rubber bushing, while still absorbing much of the NVH. The means you get a great blend of performance and comfort. Designed for street performance, drag race, and handling, and pro-touring applications, BMR upper A-arms are engineered to provide 2 additional degrees of positive caster for increased high-speed stability. Combine with BMR Lower A-arms, and you get 4 additional degrees of positive caster (2 degrees from the uppers and 2 degrees from the lowers). Added to the factory 2 degrees of caster, this allows you to achieve up to 6 degrees of total positive caster. This gives you improved geometry and increased lateral grip during cornering situations. The upper arms also have revised cross shaft geometry and shorter overall length, requiring less shim stack to achieve negative camber on lowered cars, or race and pro touring vehicles with aggressive alignments. The combination of cross shaft design and the shortened overall A-arm length gives you a improved camber curve through the front suspension’s range of motion.

Rear Suspension Kit (RSK007)
*This kit includes Part Numbers TCA034, UTCA010, and RB001*
Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR’s polyurethane, non-adjustable Rear Suspension Kit (RSK007) consists of lower control arms, upper control arms, and control arm reinforcement braces. Manufactured from heavy-duty 1.50-inch diameter, 0.120-inch wall DOM steel tubing, the lower control arms provide all the strength you’ll need for any performance application. The upper control arms are manufactured from 1.625-inch diameter, 0.120-inch wall, DOM steel tubing, strong enough for any compression load. The reinforcement braces are made from 1.0-inch diameter, 0.156-inch wall, steel tubing to help reduce frame deflection. The upper and lower control arms contain greasable, 95-durometer polyurethane bushings that add a solid, more responsive feel over the stock rubber bushings. BMR’s bushings are internally fluted, which keeps grease in the bushing, even under heavy load. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings. In addition, the reinforcement braces strengthen the upper control arm frame mounts by tying the upper mounts and lower mounts together.

BMR Suspension designed its Rear Suspension Kits to work well in street performance, drag race, and road race applications. The heavy-duty construction of the upper and lower control arms eliminate flex, giving you much improved repeatability on the street, starting line, or in the corners. BMR’s polyurethane bushings are designed to be compliant enough to give you a comfortable ride and absorb NVH, while remaining firm enough to stand up to high loads of any performance environment. The bushings easily handle the high compression loads of aggressive launches and hard acceleration, yet offer plenty of articulation for great handling. The reinforcement braces provide additional strength to the rear suspension for a more responsive driving experience. This product is the perfect upgrade for the enthusiast looking to improve performance, while maintaining acceptable NVH levels and ride quality.

Differential Bushing Kit (BK043)
These bushings are how the control arms directly connect to the differential, making them crucial to a proper functioning rear suspension system. Manufactured from 90-durometer polyurethane, BMR’s bushings kits are far superior to dry rotted, worn out, soft rubber factory bushings. Each piece is made in a precision mold, ensuring every polyurethane bushing is the exact size for your A-body. BMR’s zinc-coated steel inner sleeve resists corrosion for long life.

BMR Suspension’s BK043 kit is designed for street performance, autocross, drag race, and road race applications, or as a superior replacement bushing.
