BMR Performance Lowering Springs Set - 1" Drop - Red (SP027R) - 1979-2004 Ford Mustang
Transform the stance and handling dynamics of your classic pony car with the Performance Lowering Springs Set (SP027R) from BMR Suspension. Specifically engineered for 1979-2004 Ford Mustang platforms with solid rear axles, this complete set of four springs provides a balanced 1-inch drop across both front and rear axles. By replacing old, tired, or saggy factory coils, this kit eliminates excessive fender gap and lowers your vehicle's center of gravity. This gives you a highly stable, flat-cornering chassis that drastically cuts down on side-to-side body roll, brake dive, and rear acceleration squat, delivering modern performance handling without introducing harsh ride characteristics during street cruising.
Every spring in the SP027R kit is carefully crafted from premium high-tensile chrome silicon spring wire and cold-wound on advanced CNC coiling machinery to ensure absolute left-to-right uniformity. BMR implements a rigorous manufacturing process to guarantee elite durability: each coil is pre-compressed solid twice at the factory to establish its permanent height, stress-relieved at 750°F, and shot-peened to eliminate surface tensile forces. The front springs utilize a firm 525 lb/in linear rate for immediate steering response and front-end support, while the rear springs feature a calibrated 235 lb/in linear rate to keep the rear axle planted and composed. Finished in a high-durability red powder coat and 100% computer load-tested, this kit includes a lifetime warranty against spring sag.
