Eibach 1200.250.0325 ERS Race Main Coilover Spring

The Eibach 1200.250.0325 is a precision-engineered race main spring designed for the renowned Eibach Racing Spring System (ERS). This linear-rate coilover spring serves as the foundation of Eibach's double-spring system, providing the final spring rate that determines suspension characteristics under full compression.

ERS Double-Spring System Technology:

The ERS system utilizes a main and tender spring concept that delivers exceptional tuning flexibility. The main spring works in conjunction with a tender spring to provide a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This precise balance ensures optimal road contact while minimizing body roll, squat, and dive during aggressive driving.

Key Features:

• Linear-rate characteristic for predictable suspension response
• High spring travel and deflection capability at compact 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 indicating rate and physical dimensions
• Compatible with over 700 ERS components for unlimited suspension tuning combinations
• Individually packaged for protection during storage and shipping

This main spring is ideal for suspension engineers and motorsport enthusiasts seeking to fine-tune their race car's suspension system with professional-grade components. The ERS system's modular design allows for precise adjustment of suspension characteristics to match specific track conditions and driving styles.
