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 S197 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 SP068 for the Mustang owners who spend a lot of time at the drag strip. These springs will drop your S197 Mustang approximately 1.5-inches and feature fine-tuned spring rates to give you improved launches. The front springs are linear with a 150lb/inch rate. The rear spring is dual-rate with a working rate of 160 lb/inch. The SP068 are soft enough for great front-end travel at the drag strip. When performance and looks are a must, rely on BMR Suspension!
BMR rear springs retain the factory "hourglass" shape designed by Ford engineers. This important feature provides a "variable natural frequency" in the spring to help counteract damaging wheelhop. This is a feature of the OE springs often overlooked by other companies simply because they don't realize it's benefits in multi-purpose applications.
BMR Suspension designed the RH017 to work well in street performance, drag race, and handling applications. The differential hardware can bend or break under the large loads from engine torque. Upgrading the differential hardware is an easy way to ensure failures will be kept to a minimum. When performance is a must, rely on BMR Suspension!
***NOTE: Designed to work with BMR’s BK051 and BK054, as well as other diff inserts and lockouts on the market.***
BMR Suspension’s RH017 replacement differential hardware kit is zinc coated for long-lasting good looks. Installation time is about 3-4 hours. Proudly made in the U.S.A.
