Eibach 0700.225.0600 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Main Spring is a precision-engineered linear-rate coilover spring designed for racing and high-performance suspension applications. This spring serves as the foundation of Eibach's world-renowned ERS double-spring system, which allows suspension tuners to create custom spring rate combinations for optimal track performance and handling characteristics.

ERS Double-Spring System:

The ERS system uses a Main and Tender spring configuration that provides a softer initial rate when both springs compress together, then transitions to a firmer final rate once the tender spring fully compresses. This Main spring features a linear-rate characteristic and determines the final spring rate of the complete system. With over 700 different spring components available in the ERS lineup, builders can create nearly unlimited suspension combinations tailored to specific vehicle and track requirements.

Key Features:

• Linear-rate spring design for predictable, consistent performance
• High spring travel (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
• Block resistance for reliability at full compression
• Part number imprinted on spring indicates spring rate and physical dimensions for easy identification
• Compatible with Eibach Tender springs, Helper springs, and Connecting Plates
• Individual protective packaging

Designed for professional racing teams and serious enthusiasts who demand the ultimate in suspension tuning flexibility and performance. The ERS Main Spring transforms engine power into track adhesion through optimized wheel contact and controlled body motion during cornering, acceleration, and braking.
