BMR Performance Drag Lowering Springs Set - 1.5" Drop - Red (SP068R) - 2005-2014 Mustang GT
Dial in your S197 Mustang GT for maximum launch traction with the BMR Performance Drag Lowering Springs Set (SP068R). Purpose-engineered for Mustang owners who spend their weekends at the drag strip, this complete set of four springs provides a functional 1.5-inch drop front and rear. By lowering the vehicle's center of gravity and utilizing straight-line-optimized spring rates, this kit encourages efficient front-to-rear weight transfer, maximizing rear tire bite while giving your car an aggressive, track-ready stance.
Every spring in the SP068R kit is precision-manufactured from high-tensile chrome silicon spring wire and cold-wound on advanced CNC coiling machinery to ensure perfect left-to-right uniformity. BMR implements an exhaustive manufacturing process: each spring is compressed solid twice at the factory to establish its permanent height, stress-relieved at 750°F, and shot-peened to eliminate residual surface stresses. The front springs feature a soft 150 lb/in linear rate to maximize front-end travel and lift during launch, while the rear utilizes a 160 lb/in working dual-rate design. Crucially, the rear springs retain the factory-engineered "hourglass" shape, providing a variable natural frequency that actively counteracts axle wheel hop off the line. Finished in a durable red powder coat and computer-tested, this kit includes a lifetime warranty against spring sag.
