Eibach 1000.250.0700 ERS Race Main Coilover Spring

The Eibach 1000.250.0700 is a high-performance race main spring designed for the ERS (Eibach Race Spring) double-spring system. This linear-rate main spring provides the foundation for precise suspension tuning, delivering the muscle needed to transform engine power into optimal track adhesion through controlled body motion during cornering, acceleration, and braking.

ERS Double-Spring System:

This main spring works as part of Eibach's renowned ERS system, which combines main and tender springs to create a sophisticated two-stage rate characteristic. The system provides a softer initial rate when both springs compress together, then transitions to the firmer main spring rate once the tender spring fully compresses. With over 700 different spring components available, the ERS system offers nearly unlimited tuning combinations for suspension engineers and racing enthusiasts.

Key Features:

• Linear-rate characteristic that determines the final rate of the suspension system
• High spring travel and deflection capability with short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior corrosion protection through phosphating and epoxy coating
• Precision manufacturing with tight tolerances for consistent performance
• Part number imprinted on spring indicates spring rate and physical dimensions
• Block resistance design for extreme loading conditions
• High dynamic durability ensures extended component longevity
• Individual protective packaging to prevent damage during shipping and storage

Compatible with Eibach tender springs, helper springs, and connecting plates to create custom suspension solutions for road racing, autocross, time attack, and other motorsports applications.
