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 Silver Coilover Race Spring is designed for high-performance motorsports and adjustable coilover suspension systems. Built as part of Eibach’s renowned ERS Race Spring System, this spring delivers consistent suspension performance for applications that require precise setup control, repeatable handling, and dependable durability.\u003c\/p\u003e\u003cp\u003eEibach manufactures ERS springs in series production using advanced engineering and extensive spring-making experience. This process helps produce a highly linear spring rate with exceptionally low tolerances, allowing suspension professionals and enthusiasts to make accurate adjustments with confidence. The 2.50-inch inside diameter is compatible with coilover platforms designed for this spring size, while the silver finish provides a clean, professional appearance.\u003c\/p\u003e\u003cp\u003eWhether used for road racing, track-day driving, autocross, or other competition applications, the Eibach ERS spring is engineered to support predictable vehicle behavior under demanding conditions. Its consistent characteristics make it a practical choice for tuning ride frequency, corner balance, and overall suspension response. Verify spring rate, free length, and vehicle-specific compatibility before installation, as proper selection depends on the complete coilover configuration and intended use.\u003c\/p\u003e\u003ch3\u003eKey Product Specifications \u0026amp; Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Eibach\u003c\/li\u003e\n\u003cli\u003eProduct Line: ERS Race Spring System\u003c\/li\u003e\n\u003cli\u003ePart Number: EIB1400.250.0165S\u003c\/li\u003e\n\u003cli\u003eSpring Type: Coilover race spring\u003c\/li\u003e\n\u003cli\u003eInside Diameter: 2.50 inches\u003c\/li\u003e\n\u003cli\u003eFinish: Silver\u003c\/li\u003e\n\u003cli\u003eApplication: Automotive motorsports and adjustable coilover systems\u003c\/li\u003e\n\u003cli\u003eManufacturing Focus: Linear spring characteristics, low tolerances, and repeatable performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eOne Eibach ERS Silver Coilover Race Spring.
