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 SP076 for Shelby GT500 owners who spend a lot of time at the drag strip. These springs will drop the front end of your S197 Mustang approximately 1-inch and feature a fine-tuned spring rate to give you improved launches. The 165 lb/inch linear spring rate is soft enough for great front-end travel at the drag strip. When performance and looks are a must, rely on BMR's 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's suspensions SP076 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.
