BMR Progressive Lowering Springs 2005-11 Mustang 1.5rr/1.25fr V8.
BMR springs are specifically designed to provide optimal handling without sacrificing ride quality. The front springs are progressive wound to provide variable rates. The soft portion of the progressive winding maintains near OE ride quality. When the suspension is loaded during aggressive cornering, the springs enter into the stiffer portion of the spring. We have designed additional spring rate into this portion of the spring for better control and reduced body roll. The rear springs are linear wound with the same proven spring rate as OE. Part number SP009 will lower the front 1.25" and the rear 1.5", "levelling" the car.
Beware of low cost springs that sag over time. BMR springs are cold wound from high tensile strength chrome-silicon to provide the longest lasting, most consistent rate possible without long term "memory" loss. Always check the spring manufacturers warranty before purchasing, you definitely get what you pay for. BMR provides a lifetime warranty against spring sag. BMR rear springs retain the factory "hourglass" shape designed by Ford engineers. This important feature provides a "variable natural frequency" in the spring to help counteract damaging wheelhop. This is a feature of the OE springs often overlooked by other companies simply because they don't realize it's benefits in multi-purpose applications. Applications: |
