The H&R 60mm I.D. race spring (100mm length, 200 N/mm) is a single main racing spring crafted from lightweight 54SiCr6 spring steel. Built in Germany with extremely high-tensile wire, the thinner construction gives roughly 15% less weight and about 10% more travel than many rivals, expanding tuning capability and sharpening suspension response for track and street setups. Main springs are factory pre-blocked to prevent setting or sag. The 60mm range offers many lengths and rates plus tender springs for motorsport and Euro-spec cars such as the Porsche GT3.
