The H&R Super Sport Spring kit for 2005–2009 Ford Mustang (including Convertible), GT and Shelby variants offers deeper lowering than standard Sport Springs for an assertive performance stance while preserving ride quality. Progressive spring rates reduce body roll and lower the center of gravity to sharpen handling. Made from 54SiCr6 spring steel, shot-peened and factory pre-blocked, these springs are aimed at seasoned enthusiasts seeking refined looks and control.
