BMR lowering springs for 2015–2023 S550 and 2024 S650 Ford Mustang applications are sold as a set of four and finished in red powdercoat. These springs use CNC cold-wound chrome-silicon wire, are stress-relieved and shot‑peened to resist sag, and are factory-tested with a lifetime warranty against sag. They're tuned with specific spring rates for vehicles carrying power adders and aim to improve stance and launch characteristics.
