Eibach 0600.225.0900 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Main Spring is a precision-engineered coilover spring designed for racing and high-performance suspension applications. This linear-rate spring serves as the foundation of Eibach's renowned double-spring system, providing the final spring rate that determines handling characteristics under cornering, acceleration, and braking loads.

ERS Double-Spring System:

The ERS system combines Main and Tender springs to create a dual-rate suspension setup. When both springs compress together, the system provides a softer initial rate for improved road contact and compliance. Once the tender spring reaches full compression, the Main spring alone determines the firmer ending rate for reduced body roll and squat. This sophisticated approach delivers the precise balance needed to transform engine power into optimal traction.

Key Features:

• Linear-rate characteristic determines final suspension rate
• Shot-peened surface treatment for enhanced fatigue resistance
• High spring travel and deflection capability at compact mounting lengths
• Phosphate and epoxy coating for superior corrosion protection
• Precision manufacturing with tight tolerances for consistent performance
• Part number imprinted on spring indicates rate and physical dimensions
• High dynamic durability for extended service life
• Block resistance prevents coil binding
• Compatible with over 700 ERS components for custom tuning

The Eibach ERS system allows suspension engineers and enthusiasts to create virtually unlimited spring combinations from standardized components. Each spring is individually packaged and clearly marked for easy identification during setup and tuning.
