The H&R Sport Spring kit for 2005–2010 Pontiac G6 reduces ride height to improve stance, lowers the center of gravity and helps control body roll for more confident cornering and a cleaner look. Made from shot‑peened 54SiCr6 spring steel with a progressive spring rate, these lightweight, resilient springs are tuned for superb ride quality while sharpening handling and are H&R’s best-selling kit from Germany.
