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\u003e\u003cstrong\u003eBrief Description:\u003c\/strong\u003e The Eibach ERS coil-over race spring is engineered for high-performance suspension applications that demand consistent spring behavior, precise tuning, and dependable quality. Designed for professional and enthusiast racing environments, this spring is manufactured as part of Eibach’s established ERS Race Spring System.\u003c\/p\u003e\u003cp\u003eEibach produces ERS springs in repeatable series production using extensive spring-manufacturing experience. This process helps deliver a highly linear spring rate, tight production tolerances, and consistent performance from one spring to the next. The result is more predictable suspension response and greater control when tuning a race vehicle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePerformance Benefits:\u003c\/strong\u003e The Eibach ERS spring supports accurate suspension setup changes by providing a dependable, repeatable spring rate.
