The H&R 60mm I.D. race spring is a single main spring (200mm length, 100 N/mm or 571 lbs/in) for fine suspension tuning in motorsport and track applications. Made in Germany from lightweight (hf) 54SiCr6 spring steel, the 2.50" I.D. program is typically 15% lighter and provides roughly 10% more travel than comparable springs. Each spring is pre‑blocked to resist sagging; H&R offers many lengths and rates along with tender springs and coverage that includes Porsche GT3 and other Euro‑spec cars.
