The H&R 60mm I.D. race spring is a single 60mm main spring with a 50 N/mm (286 lbs/in) rate for precise suspension adjustment. Produced in Germany from special (hf) 54SiCr6 spring steel, these springs are around 15% lighter and provide about 10% more travel than comparable designs. H&R’s extensive 60mm line covers many lengths and rates and includes tender springs; every spring is factory pre-blocked to prevent setting or sag and the range includes options for Porsche GT3 and other Euro-spec cars.
