The H&R 60mm I.D. race spring is a single main spring (250mm length, 40 N/mm or 229 lbs/in) for track and competition suspension tuning. Made in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. series is on average 15% lighter and provides about 10% more travel compared with competitors. Springs are pre‑blocked to prevent permanent set; H&R's comprehensive 60mm I.D. program offers many lengths, spring rates and tender springs and includes coverage for Porsche GT3 and other Euro‑spec vehicles.
