Increase cornering ability and improve the cosmetic appeal of your S550 and S650 GT350 Mustang with a set of Lowering Springs from BMR's suspension! Stock springs can sag, get rusty, and simply wear out over a long period of time. BMRs Rear Handling Lowering Springs (SPH767) lower your vehicle and are designed for street performance and hardcore applications. When performance is a must, rely on BMR's suspension!
