Eibach 0600.225.0300 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) main coilover spring is engineered to deliver precision suspension tuning for racing and high-performance applications. This linear-rate main spring serves as the foundation of Eibach's renowned double-spring system, providing the muscle needed to transfer engine power to the track through optimized tire adhesion.

ERS Double-Spring System Benefits:

The ERS system combines main and tender springs to create a sophisticated two-stage rate characteristic. When both springs compress together, the system provides a softer initial rate for superior road compliance and grip over surface irregularities. Once the tender spring fully compresses, the main spring's linear rate takes over, delivering the firmer ending rate needed to control body roll, squat, and dive during aggressive cornering, acceleration, and braking.

Key Features:

• Linear-rate characteristic determines the final rate of the suspension system
• Compatible with over 700 ERS components for virtually unlimited tuning combinations
• High spring travel and deflection capability within compact mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Precision wound to exact tolerances for consistent performance
• Superior corrosion protection through phosphating and epoxy coating
• Part number imprinted directly on spring indicating rate and dimensions
• Designed to work with ERS tender springs, helper springs, and connecting plates

Each spring is individually packaged and clearly marked for easy identification. Eibach's rigorous manufacturing process ensures exceptional dynamic durability and component longevity, making these springs the choice of professional race teams and serious enthusiasts worldwide.
