The H&R Sport Spring kit for 1999-2004 Ford Mustang Cobra Convertible V8 (with IRS) lowers ride height to reduce fender‑well gaps, drop the center of gravity and reduce body roll for improved handling while a progressive spring rate preserves a comfortable ride. Made from 54SiCr6 spring steel, shot‑peened and block‑set for strength and lightness; these top‑selling H&R springs are made in Germany.
