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 Coil-Over Race Spring is engineered for professional-level suspension tuning, motorsports applications, and performance-focused builds that require predictable spring behavior. Part number Eibach 0400.200.1900 features a 400 lb\/in spring rate and is designed for compatible coil-over suspension systems using a 2.00-inch inside diameter spring platform.\u003c\/p\u003e\u003cp\u003eEibach ERS race springs are manufactured in repeated series production, combining extensive manufacturing experience with strict quality control. This process helps deliver a highly linear spring characteristic, consistent performance, low production tolerances, and dependable handling response. The result is a spring that allows racers and suspension tuners to make precise setup changes while maintaining confidence in the vehicle’s balance and behavior.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBrief Description:\u003c\/strong\u003e A precision-manufactured Eibach ERS coil-over spring for race and high-performance suspension applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Product Specifications \u0026amp; Technical Data:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Eibach\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e ERS Race Spring System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0400.200.1900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate:\u003c\/strong\u003e 400 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Type:\u003c\/strong\u003e Coil-over race spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter:\u003c\/strong\u003e 2.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Automotive racing and performance suspension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing Focus:\u003c\/strong\u003e Linear rate characteristics, low tolerances, and repeatable quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included in the Box:\u003c\/strong\u003e One Eibach ERS coil-over race spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Universal motorsports-style fitment for compatible coil-over suspension systems.
