Product Details
These BMR Suspension Rear Lowering Springs (1.25" Drop) fit the 1993-2002 Pontiac Firebird (4th Gen). BMR Suspension's Rear Lowering Springs for the 4th Gen Firebird drop your car for a lower center of gravity and a flatter cornering attitude. The linear spring rate keeps daily driving comfortable while clamping down on body roll, squat under throttle, and nose-dive under braking.
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. BMR backs every spring with a lifetime warranty against sag.
