The Eibach ERS coilover spring, 3.00-inch inner diameter, is part of Eibach's Race Spring System and targets applications needing a smaller I.D. for rear or custom coilover builds. ERS springs are produced to achieve consistent, linear rates with tight tolerances across series production. Verify compatibility with your shock and spring perch dimensions before fitting.
