The H&R Sport Spring for 2005–2009 Ford Mustang including Convertible, GT, Shelby GT and Shelby GT-H (V6/V8) is a lowering spring kit that tightens fender gaps, lowers the center of gravity and reduces body roll to sharpen handling. Its progressive-rate springs use shot-peened 54SiCr6 steel in a block-set design to lower ride height while preserving comfort. Made in Germany and H&R's best-selling spring, the kit also helps reduce wind resistance and can modestly improve fuel economy.
