Description
Give your S550 and S650 Mustang an aggressive look and improve handling with a set of Lowering Springs from BMR Suspension! Stock springs can sag, get rusty, and simply wear out over a long period of time. BMR’s Rear Lowering Springs (SP085) improve the performance of your vehicle and are designed primarily for handling applications. When performance is a must, rely on BMR Suspension!
