The H&R 60mm I.D. race spring is a single main spring (250mm length, 120 N/mm or 686 lbs/in) suitable for motorsport and custom suspension builds. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. program tends to be 15% lighter and offers about 10% more travel than comparable springs. Each spring is pre‑blocked to prevent sagging; H&R's extensive 60mm I.D. lineup includes many lengths and rates, tender spring options, and coverage that includes Porsche GT3 and other Euro‑spec cars.
