The Eibach ERS 120mm coil-over spring is part of Eibach's ERS Race Spring System, produced in series to deliver a highly consistent, linear spring characteristic with tight tolerances. Built for repeatable results, it emphasizes predictable spring rate and high manufacturing quality, intended for suspension builds that call for a 120mm length and a 60mm inner diameter specification.
