The Eibach ERS coil-over spring is a 225mm length x 70mm ID race spring for coilover use. As a member of Eibach's ERS Race Spring System, it benefits from series production that keeps tolerances low and spring characteristics consistent. That repeatable manufacturing supports predictable handling and dependable build quality for track-focused or heavily modified street suspension setups where precision matters.
