Product Details
BMR Suspension Handling Lowering Springs for the 2015-2023 Ford Mustang GT (S550) step up in spring rate over the Performance version for drivers who spend real time on autocross courses, road-course track days, or fast back-roads. The firmer tune controls body roll and keeps camber curves working when loads build up in long, high-speed sweepers.
All BMR Suspension springs are cold-wound on CNC coiling machines from chrome silicon high-tensile spring wire, compressed solid twice for permanent set, stress-relieved at 750°F, shot-peened, and computer-tested one at a time. That level of process control is why BMR backs every spring with a lifetime warranty against sag. Proudly manufactured in the U.S.A.
