The Eibach ERS coil-over spring is a 200mm length x 70mm ID race spring for coilover use. Part of Eibach's ERS Race Spring System, it achieves a highly linear rate with tight manufacturing tolerances through series production. That repeatable construction provides consistent handling and reliable build quality for track and tuned-street applications.
