BMR Suspension SP012 rear lowering springs for 2005–2014 S197 Mustang GT/GT500 lower the rear 1.5 inches and use a tuned 160lb rear rate to balance handling and ride. Rear springs retain the factory hourglass shape to provide a variable natural frequency that helps counteract wheelhop. Built with chrome silicon wire, CNC coiling, stress relief and shot-peening, they come in red powdercoat for corrosion resistance and appearance.
