Product Details
BMR Suspension's Rear Lowering Springs for the 1993-2002 Pontiac Firebird (4th Gen) drop your car for a lower center of gravity, flatter cornering attitude, and the aggressive stance this platform deserves. 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. That level of process control is why BMR backs every spring with a lifetime warranty against sag. Proudly manufactured in the U.S.A.
