Eibach 0600.225.0750 ERS Race Main Coilover Spring

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

ERS Double-Spring System:

The ERS system utilizes a Main and Tender spring configuration 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 Main spring features a linear-rate characteristic and determines the final suspension rate of the system. With over 700 different spring components available, suspension engineers and enthusiasts can create virtually unlimited combinations tailored to specific vehicle requirements and track conditions.

Key Features:

• Linear-rate characteristic for predictable suspension behavior
• High spring travel and deflection capability at compact mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Precision-wound with tight tolerances for consistent performance
• Superior corrosion protection through phosphating and epoxy coating
• Block resistance design prevents coil binding
• Imprinted with part number, spring rate, and physical dimensions for easy identification
• High dynamic durability for extended component longevity
• Individual protective packaging to prevent damage during shipping and storage

Application Notes:

This Main spring is designed to work with Eibach Tender springs (which determine initial rate), Helper springs (which prevent spring looseness at full droop), and Connecting Plates (which join Main and Tender springs). The modular ERS system allows precise suspension tuning to balance ride compliance with body control, ensuring optimal tire contact and vehicle stability under all driving conditions.
