The H&R 60mm I.D. race spring is a single 40mm spring with a 30 N/mm (171 lbs/in) rate for tailored suspension setups. Made in Germany from lightweight (hf) 54SiCr6 spring steel, H&R’s 60mm springs are about 15% lighter and yield roughly 10% more travel than comparable products. The line includes many main and tender springs for custom tuning; each spring is pre-blocked to prevent setting or sag and the program covers Porsche GT3 and other Euro-spec applications.
