There is nothing like the aggressive look of a car with the right stance! BMR Suspension believes the right springs go beyond looks—your 2015-2023 S550 Mustang 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 SPD763 for the power adder crowd who want great all-around performance without worrying about the front-end sitting too low. These springs are designed for vehicles with the extra front-end weight of a supercharger or turbocharger kit. These lowering springs feature a fine-tuned spring rate (170 lb/inch front, 800lb/inch rear) to give you great performance and a smooth ride. The linear spring rates offers plenty of support, while remaining soft enough for great weight transfer. When performance and looks are a must, rely on BMR Suspension!

BMR Suspension’s SPD763 lowering springs are available in red powdercoat for long-lasting good looks. Front and rear springs are available separately (SP089 front, SP088 rear). Installation time is about 3-4 hours. Proudly made in the U.S.A.

NOTE:

This product is designed for V8 boosted applications where there is an increase in weight over the front suspension

Designed to work with OE mounts and perches or Camber Plates that re-use the OE perch. Aftermarket perches (Vorshlag) may not fit properly and could lead to excessive NVH.
