Eibach 1400.250.0080 ERS Race Main Coilover Spring

The Eibach 1400.250.0080 is a precision-engineered race main spring designed for Eibach's renowned ERS (Eibach Race Spring) double-spring system. This high-performance coilover spring delivers the muscle needed to transform engine power into optimal track adhesion through precisely tuned suspension dynamics.

ERS Double-Spring System Technology:

The ERS system utilizes a Main and Tender spring concept that provides sophisticated rate progression. When both springs compress together, the system delivers a softer initial rate for improved road contact and compliance. Once the tender spring fully closes, the Main spring's linear-rate characteristic takes over, providing the firmer ending rate needed for controlled body roll, reduced squat, and minimized dive during aggressive cornering, acceleration, and braking.

Key Features:

• Linear-rate main spring characteristic determines final system rate
• Compatible with over 700 different ERS spring components for unlimited tuning combinations
• High spring travel and deflection capability with short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability and component longevity
• Precision manufacturing with tight tolerances
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Block resistance design for maximum performance
• Individual protective packaging

This main spring works in conjunction with Eibach Tender springs (available in linear and progressive rates), Helper springs (for preventing spring-seat looseness at full droop), and Connecting Plates to create a fully customizable suspension system. Ideal for serious racers and weekend enthusiasts seeking precise suspension control and unmatched performance flexibility.
