Fits 1967-1972 GM A-Body vehicles, including Chevrolet Chevelle, El Camino, and Monte Carlo; Buick Gran Sport and Skylark; Oldsmobile 442 and Cutlass; and Pontiac GTO and LeMans.

Improve the stance and handling of your GM A-body with the BMR Suspension SP031R lowering spring kit. This set of four springs provides a consistent 2-inch drop, lowering the center of gravity to reduce body roll in corners while maintaining a street-friendly ride quality. Designed for enthusiasts who demand performance without sacrificing daily drivability, these springs replace worn or sagging factory coils with precision-engineered components.

BMR manufactures these springs from chrome silicon high-tensile spring wire. Each coil is cold-wound on a CNC coiling machine to ensure exact diameter consistency and matched spring rates across the set. To prevent future sag, every spring is compressed solid twice at the factory to establish a permanent set. The manufacturing process includes stress-relieving at 750 degrees Fahrenheit and shot-peening to eliminate surface stresses, significantly extending the service life of the material.

Improve your classic's stance and handling with the BMR Suspension SP030R lowering spring kit. Designed for street performance, these springs provide a 1-inch drop from stock height, lowering the center of gravity to reduce body roll while maintaining enough compliance for a comfortable ride. Unlike standard replacement springs that may sag over time, these units are engineered for long-term durability and consistent ride height.

• Precision Engineering: Cold-wound on a CNC coiling machine using high-tensile chrome silicon spring wire for exact tolerances.
• Stress-Relieved & Shot-Peened: Stress-relieved at 750°F to remove winding-induced tension and shot-peened to eliminate residual surface stresses.
• Preset for Performance: Each spring is compressed solid twice at the factory to give it a permanent set, guaranteeing no sag over the life of the part.
• Individual Testing: Every spring is computer-tested using a CNC load cell to verify spring rates before leaving the facility.
• Durable Finish: Finished in a vibrant red powdercoat for superior corrosion resistance and long-lasting aesthetics.

Fits 1979-2004 Ford Mustang models, including Base, GT, LX, SVO, and select SVT Cobra (excludes 1999-2004 models with Independent Rear Suspension).

Upgrade your Fox Body or SN95 Mustang's stance and handling with BMR Suspension SP029R rear lowering springs. Designed for street performance enthusiasts, these springs provide a functional 1-inch drop to eliminate factory wheel gap and lower the vehicle's center of gravity. BMR utilizes a linear spring rate to maintain a smooth, comfortable ride while providing the necessary support to keep the chassis level during aggressive cornering.

Every BMR spring is manufactured from chrome silicon high-tensile wire and cold-wound on CNC coiling machines for exact side-to-side consistency. To ensure long-term durability, each spring is stress-relieved at 750°F and shot-peened to eliminate residual surface stresses. BMR pre-sets every spring by compressing it solid twice at the factory, guaranteeing the ride height will not sag over time.

• Manufacturer Part Number: SP029R
• Drop Height: 1-inch (Rear)
• Spring Rate: Linear
• Material: CNC cold-wound chrome silicon high-tensile wire
• Finish: Red powdercoat
• Installation: Estimated 2-3 hours; replaces factory rear springs
• Warranty: Lifetime warranty against spring sag

Fits select 1979-2004 Ford Mustang models, including Base, GT, LX, SVO, and SVT Cobra.

Improve your Mustang's stance and handling with BMR Suspension SP028R Front Lowering Springs. Designed for street performance, these springs provide a 1-inch drop to lower the vehicle's center of gravity, reducing body roll and improving cornering stability. The linear spring rate provides predictable handling and sufficient support during aggressive driving while maintaining enough compliance for a comfortable daily ride.

Every BMR spring is cold-wound from chrome silicon high-tensile wire on CNC coiling machines to ensure exact diameter consistency between the left and right sides. To guarantee long-term durability, the springs are stress-relieved at 750°F and shot-peened to eliminate residual surface stresses. Each unit is compressed solid twice at the factory to set its permanent height and is computer-tested for precise load tolerances, allowing for a lifetime warranty against spring sag.
