Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.\n\u003cp\u003eThe Eibach ERS 250mm Length x 70mm ID Coil-Over Spring is engineered for racing applications that demand predictable handling, consistent response, and dependable performance. As part of Eibach’s renowned ERS Race Spring System, this coil-over spring is manufactured in repeated series production using Eibach’s extensive spring-development expertise.\u003c\/p\u003e\u003cp\u003eEibach ERS springs are designed to deliver a highly linear spring rate with exceptionally tight manufacturing tolerances. This consistency helps suspension tuners make precise setup changes and allows the spring to perform predictably throughout its operating range. The 45 lb\/in rate is well suited to custom coil-over suspension systems where controlled suspension movement and repeatable track performance are priorities.\u003c\/p\u003e\u003cp\u003eBuilt for professional and enthusiast motorsport use, the spring features a 70mm inside diameter and 250mm free length for compatibility with appropriately sized coil-over components. Its compact race-oriented design supports installation in applications where accurate spring selection is essential. Eibach quality control and proven manufacturing processes provide reliable performance for circuit racing, autocross, time attack, and other competition-focused builds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eibach ERS coil-over race spring.
