The H&R 60mm I.D. race spring is a single main spring (250mm length, 90 N/mm or 514 lbs/in) intended for motorsport suspension tuning and custom setups. Produced in Germany using lightweight (hf) 54SiCr6 spring steel, H&R's 2.50" I.D. lineup delivers about 15% less weight and roughly 10% more travel than competitor springs. Springs are factory pre‑blocked to resist sagging; the program includes many lengths and rates, tender springs, and coverage that includes Porsche GT3 and other Euro‑spec applications.
