BMR Progressive Lowering Springs 2005+ Mustang 1.5rr/1.25fr.

This is for a set of rear springs only BMR progressive wound springs are specifically designed with improved spring rates to provide optimal handling without sacrificing ride quality. 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. They are available in two variations. Lowers the front 1.25" and the rear 1.5". Our rear springs retain the factory "hourglass" shape designed to provide the required "variable natural frequency" that controls wheelhop.

Beware of low cost springs that sag over time. BMR springs are cold wound from high tensile strength chrome-silicon-vanadium 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.

NOTE: Sold in BMR red only.
