BMR 05-07 Mustang GT Progressive Lowering Springs (1.25"Front / 1.75" Rear )

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. Part number SP009 will lower the front 1.25" and the rear 1.75". Part number SP010 lowers the front 1.5" and the rear 2". Both kits are designed to "level" the car. 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.
