The H&R 60mm I.D. race spring is a single main spring (250mm length, 80 N/mm or 457 lbs/in) for precise suspension tuning and competitive use. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. program averages 15% less weight and about 10% more travel than comparable springs. Each spring is pre‑blocked to prevent permanent set; H&R offers a broad selection of lengths and rates plus tender springs and coverage that includes Porsche GT3 and other Euro‑spec cars.
