The H&R 60mm I.D. race spring is a single race spring 150 mm long with a spring rate of 170 N/mm (about 971 lbs/in), intended for fine suspension tuning in motorsport and performance street applications. Manufactured in Germany from lightweight 54SiCr6 spring steel, this 60mm program uses thinner, high-tensile wire to reduce weight by about 15% and increase travel by roughly 10% compared with many competitors. H&R offers extensive lengths and rates, including tender springs, and pre-blocks them to resist sag.
