The H&R 60mm I.D. race spring (100mm length, 130 N/mm) is a single main racing spring made from special lightweight 54SiCr6 spring steel. Made in Germany using a high-tensile wire alloy, H&R’s thinner wire design delivers roughly 15% less weight and about 10% more travel than many competitors, giving tuners a wider adjustment window and more responsive handling. Main springs are factory pre-blocked to prevent setting or sag. The 60mm program offers many lengths and rates and tender springs for motorsport and Euro-spec cars like the Porsche GT3.
