The H&R 60mm I.D. race spring is a single main spring (250mm length, 60 N/mm or 343 lbs/in) for motorsport and custom suspension builds. Produced in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. program typically weighs about 15% less and yields approximately 10% more travel than comparable springs. Springs arrive pre‑blocked to avoid sagging; H&R's 60mm I.D. range includes numerous lengths and rates, tender springs, and coverage suitable for Porsche GT3 and other Euro‑spec cars.
