The Eibach ERS coil-over spring (18.00 in. length x 3.75 in. ID) is part of Eibach's Race Spring System, manufactured in series to achieve a linear spring characteristic with minimal tolerances. ERS race springs are produced with tight quality control to provide predictable rates and consistent behavior under repeated use, making them suitable for competition or high-demand track environments where precise spring response and repeatability are required.
