BMR 1.5" Rear Handling Lowering Springs - Red (SP067R) - 2005-2014 Mustang GT / 2007-2014 Shelby GT500
Enhance the cornering stability and stance of your S197 Mustang with the Rear Handling Lowering Springs (SP067R) from BMR Suspension. Specifically engineered for enthusiasts who frequent the road course or autocross, these rear springs provide a functional 1.5-inch drop that eliminates factory rear-end rake and lowers your vehicle's center of gravity. By utilizing a precision-tuned 200 lb/in linear spring rate, this kit significantly decreases body roll and ensures a flat, predictable chassis through high-speed turns, providing superior driver control without sacrificing ride composure.
Every BMR rear spring is crafted from premium high-tensile chrome silicon spring wire and cold-wound on CNC coiling equipment to achieve strict architectural uniformity between the left and right sides. BMR’s strict manufacturing process includes compressing each coil solid twice to set its permanent height, stress-relieving them at 750°F, and shot-peening them to eliminate residual surface stresses. Crucially, these springs retain the factory-designed "hourglass" shape, which introduces a variable natural frequency that counteracts wheel hop—a crucial engineering nuance omitted by many aftermarket competitors. Finished in a durable red powder coat, every individual spring is computer-tested for precise height and rate compliance and backed by a lifetime warranty against sag.
