The H&R 60mm I.D. race spring is a single 300mm main spring with a 45 N/mm (257 lbs/in) rate, built for precise suspension tuning. Made in Germany from special lightweight (hf) 54SiCr6 spring steel, these springs are typically 15% lighter and offer about 10% more travel than comparable springs. H&R pre-blocks springs to prevent setting or sag, and the 60mm program covers Porsche GT3 and other Euro-spec applications.
