Eibach ERS Formula Race Spring eibC900, 36mm Inner Diameter

Eibach's ERS line has evolved over the years to be the world's most prominent, comprehensive and superior Race Spring System. 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.

The Eibach ERS Formula Spring eibC900 is engineered for professional and competition-focused suspension systems that require consistent, predictable spring performance. As part of the Eibach ERS line, this race spring benefits from extensive development and repeated series production, helping deliver dependable handling characteristics across demanding track applications.

Eibach manufactures its Race Springs to maintain a highly linear spring rate with tight production tolerances. This controlled response allows suspension tuners and race teams to make precise setup changes while preserving consistent performance during repeated laps and changing operating conditions. The 36mm inner diameter supports compatibility with spring hardware designed for this specification.

Built for automotive racing and performance suspension use, the Eibach Formula Spring combines manufacturing consistency with the quality expected from a leading suspension component manufacturer. It is well suited for custom coilover systems, motorsport suspension assemblies, and applications where accurate spring behavior is essential. Verify the required spring rate, free length, installed height, and suspension hardware before ordering to ensure proper system compatibility.
