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 SP077 for the street performance crowd who want to use their cars in a variety of applications. These springs will drop your V-8-equipped 2010 and newer Camaro 1.25-inch, and feature a fine-tuned spring rate to give you great handling and a smooth ride. The 460 lb/in 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. The lowered stance and increased spring rate decreases body roll and gives you a lower center of gravity for increased driver control in aggressive cornering situations. Combine this with BMR adjustable sway bars and you have the ultimate in handling and performance. When performance and looks are a must, rely on BMR's suspension!BMR's suspensions SP079 lowering springs are available in red powdercoat for long-lasting good looks. Installation time is about 2-3 hours. Proudly made in the U.S.A.
