The H&R 60mm I.D. race spring (100mm length, 70 N/mm) is a single main race spring crafted from (hf) 54SiCr6 spring steel. Built in Germany with extremely high-tensile wire, H&R’s thinner wire design delivers about 15% less weight and roughly 10% more travel than many competitors, giving tuners an expanded adjustment range and sharper handling feedback. Main springs are factory pre-blocked to prevent setting or sag. The comprehensive 60mm line offers many lengths and rates plus tender springs for motorsport and Euro-spec cars such as the Porsche GT3.
