There is nothing like the aggressive look of a car with the right stance! Over time, stock springs sag, get rusty, and simply wear out. BMR Suspension believes the right springs go beyond looks?your F-Body needs to perform, too! 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 SP090 for the handling crowd who regularly use their cars on the road course or for autocross. These springs will drop your Fourth Gen F-Body 1.25-inches, and feature a fine-tuned spring rate to give you great handling and a smooth ride. The 725 lb/in front and 210 lb/in rear spring rates offer plenty of support, keeping the body flat and level in the corners. 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.
