Eibach 0700.225.1100 ERS Race Main Coilover Spring

The Eibach 0700.225.1100 is a precision-engineered Race Main Spring designed for the ERS (Eibach Race Spring) system. This linear-rate coilover spring transforms engine power into track performance through optimized suspension tuning and maximum adhesion.

ERS Double Spring System:

This Main spring is part of Eibach's acclaimed ERS double-spring system, which combines Main and Tender springs to achieve optimal suspension balance. The system delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. With over 700 different spring components available, the ERS system offers nearly unlimited combination possibilities for precise suspension tuning.

Key Features:

• Linear-rate characteristic determines the final rate of the suspension system
• High spring travel and deflection delivers high end loads at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability ensures extended component longevity
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Part number imprinted on spring indicates spring rate and physical dimensions
• Compatible with Eibach Tender springs, Helper springs, and Connecting Plates
• Individual protective packaging for safe storage and handling

Engineered to reduce body roll, squat, and dive during cornering, acceleration, and braking while maintaining permanent road contact over irregular surfaces. Ideal for racing applications and enthusiasts seeking professional-grade suspension performance.
