The H&R Sport Spring kit for 2011–2014 Ford Mustang, including convertible and GT V6/V8 models, lowers ride height to reduce fender gap and sharpen handling. Its progressive spring rate lowers the center of gravity and reduces body roll, improving stability and cornering response while offering a slight aerodynamic gain. Constructed from 54SiCr6 spring steel, shot‑peened and lightweight to balance durability with comfortable ride quality.
