The H&R 60mm I.D. race spring is a single main spring (250mm length, 100 N/mm or 571 lbs/in) for track and race suspension tuning. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. program is typically 15% lighter and provides about 10% more travel than comparable springs. Each unit is pre‑blocked to avoid setting; H&R's 60mm I.D. range offers extensive lengths and rates plus tender springs and includes coverage for Porsche GT3 and other Euro‑spec cars.
