The H&R 60mm I.D. race spring is a single main spring (200mm length, 140 N/mm or 800 lbs/in) for high‑demand suspension tuning. Built in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. series averages 15% less weight and about 10% more travel than comparable springs. Each spring is pre‑blocked to resist setting; H&R's 60mm I.D. program includes many lengths and rates, tender springs, and coverage suitable for Porsche GT3 and other Euro‑spec vehicles.
