The H&R 60mm I.D. race spring is a single main spring (200mm length, 150 N/mm or 857 lbs/in) for precision racing and track use. Produced in Germany from lightweight (hf) 54SiCr6 spring steel, H&R's 2.50" I.D. offerings are on average 15% lighter and offer about 10% more travel than competitors' springs. Springs are pre‑blocked to prevent permanent set; the 60mm I.D. program supplies a wide selection of lengths, rates and tender spring options and includes coverage for Porsche GT3 and other Euro‑spec cars.
