BMR Rear Performance Lowering Springs - 1" Drop - Red (SP029R) - 1979-2004 Ford Mustang
Level out your vehicle's stance and sharpen its cornering dynamics with the Rear Performance Lowering Springs (SP029R) from BMR Suspension. Purpose-built for the popular Fox Body and SN95 1979-2004 Ford Mustang platforms with solid rear axles, this pair of rear coils lowers the rear end by a precise 1 inch. By correcting uneven factory ride height and replacing tired, saggy original springs, this kit effectively lowers your vehicle's center of gravity. The result is a more aggressive profile, reduced body roll, and minimized rear-end squat during acceleration, providing crisp street performance while preserving standard ride comfort.
Every rear spring in the SP029R kit is meticulously crafted from premium high-tensile chrome silicon spring wire and cold-wound on state-of-the-art CNC coiling machinery to guarantee side-to-side consistency. BMR employs a thorough manufacturing regiment to ensure lasting 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 stresses. Engineered with a firm, 235 lb/in linear spring rate, these coils keep the rear axle stable and tracking predictably under load. Finished in an impact-resistant red powder coat and 100% computer load-tested, this rear set carries a lifetime warranty against spring sag.
