Eibach 0800.250.0150 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) system provides the precision spring tuning needed to transform engine power into optimal track adhesion through superior suspension control. This race main spring is part of Eibach's world-renowned modular spring system, offering racing professionals and enthusiasts the ability to fine-tune suspension characteristics for maximum performance.

ERS Double Spring System:

The ERS system utilizes a sophisticated Main and Tender spring concept that delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This race main spring features a linear-rate characteristic and determines the final rate of the complete system. With over 700 different single spring components available, the ERS system enables nearly unlimited suspension tuning combinations.

Key Features:

• Linear-rate characteristic for predictable performance
• High spring travel and deflection capability with short mounting lengths
• Block resistance for consistent bottom-out protection
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component life
• Precision manufacturing with tight tolerances
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and dimensions
• Compatible with Eibach connecting plates for tender spring integration

Each spring is individually packaged for protection and easy identification. The ERS system's modular design allows suspension engineers to create custom spring combinations from stock components, providing unmatched flexibility for race applications across multiple motorsports disciplines.
