Product Details

BMR Suspension Drag Lowering Springs for the 2015-2023 Ford Mustang GT, V6, and EcoBoost (S550) use a deliberately soft front spring rate to maximize weight transfer onto the rear tires at launch, paired with a firmer rear rate that plants the contact patches and quickens 60-foot times. Built for drag-focused S550s that live at the strip.

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.
