The H&R Sport Spring kit for 1999-2004 Mazda Protege, Protege5 and Protege MP3 (BJ) reduces ride height to tighten fender‑well gaps, lower the center of gravity and reduce body roll for improved handling, while a progressive spring rate preserves comfort. Made from 54SiCr6 spring steel with shot‑peening and block setting for resilience and lightness; H&R’s top‑selling springs are produced in Germany.
