Fits 1979-2004 Ford Mustang models including LX, GT, SVT Cobra, and SVO. This BMR Suspension lowering spring kit (SP027R) is designed for street performance enthusiasts seeking an aggressive stance without sacrificing ride quality.

Stock springs often sag and lose their rate over decades of use. These BMR springs provide a consistent 1-inch drop, lowering the center of gravity for improved handling while maintaining a smooth, comfortable ride. Each spring features a linear rate to keep the chassis flat and level through corners. To ensure maximum durability, these springs are cold-wound from chrome silicon high-tensile wire on CNC coiling machines and are double-compressed at the factory to provide a permanent set that prevents future sagging.

Every spring is stress-relieved at 750°F and shot-peened to eliminate residual surface stresses. BMR computer-tests every individual spring in a load cell to verify precise spring rates before shipping. Finished in a durable red powdercoat, this kit is built for long-term performance and aesthetics.
