The H&R 60mm I.D. race spring is a single 60mm spring with a 25 N/mm (143 lbs/in) rate for refined suspension tuning. Built in Germany from special (hf) 54SiCr6 spring steel, these springs are typically 15% lighter and provide about 10% more travel than comparable options. H&R’s 60mm program offers many lengths and rates along with tender springs for maximum travel; each unit is factory pre-blocked to avoid sag and includes fitment options for Porsche GT3 and other Euro-spec vehicles.
