The Eibach ERS coil-over spring is a precision race spring for coilover applications, supplied as a 5.00 in length with a 2.25 in inner diameter. It provides a compact, repeatable spring element for track and competition suspension setups where predictable response matters. The ERS line has evolved into a comprehensive race spring system produced in series to deliver highly linear rates, low tolerances and consistent manufacturing quality.
