The H&R 60mm I.D. race spring (100mm length, 160 N/mm) is a single main race spring crafted from lightweight 54SiCr6 spring steel. Manufactured in Germany with high-tensile wire alloy, the thinner construction provides about 15% less weight and roughly 10% more travel than comparable springs, delivering a broader tuning range and more responsive suspension behavior. H&R pre-blocks main springs to prevent settling or sag. The comprehensive 60mm program offers many lengths and rates plus tender springs for motorsport and Euro-spec cars like the Porsche GT3.
