The Eibach ERS 8.00" x 2.50" coilover spring with a 400 lb rate is a race‑oriented replacement spring from Eibach’s ERS line. ERS springs are produced in series to deliver a highly linear spring characteristic with tight manufacturing tolerances. That consistency yields repeatable spring rates and predictable response, making these race springs suitable where consistent, measurable spring behavior is required.
