The Eibach ERS coilover spring is a race-grade spring measuring 170 mm in length with a 60 mm inside diameter. Part of Eibach’s ERS Race Spring System, it’s manufactured in series to achieve a linear spring rate, the lowest tolerances, and high quality through repeated, experienced production. That consistency makes it ideal for coilover and track-focused suspension where predictable, repeatable behavior matters.
