BMR Suspension SP012R Rear Performance/Drag Lowering Springs for 2005-2014 Ford Mustang - Red

Fits all 2005-2014 Ford Mustang models (Base, GT, Boss 302, Bullitt, and Shelby GT500).

Optimize your S197’s stance and launch consistency with BMR Suspension SP012R Rear Performance/Drag Lowering Springs. These springs are designed to replace factory rear coils, providing a lower center of gravity and improved weight transfer for performance and drag racing applications. By reducing the rear ride height, these springs eliminate the excessive wheel gap typical of stock Mustangs while offering the spring rate necessary for aggressive street and track use.

Engineering for durability, BMR manufactures these springs from chrome silicon high-tensile spring wire. Each coil is cold-wound on a CNC machine to ensure exact tolerances and matching rates across the pair. To prevent sagging, every spring is compressed solid twice at the factory to establish its permanent set. The manufacturing process includes stress-relieving at 750°F and shot-peening to eliminate surface stresses and fatigue, ensuring these springs maintain their height and performance under heavy loading.
