Eibach 1000.250.0200 ERS Race Main Coilover Spring 10 inch 2.5 ID 200 lb/in

The Eibach 1000.250.0200 is a precision-engineered race main spring designed for the company's renowned ERS (Eibach Race Spring) double-spring suspension system. This linear-rate coilover spring features a 2.5-inch inner diameter, 10-inch free length, and 200 lb/in spring rate, providing the foundation for fine-tuned suspension performance in racing and high-performance applications.

ERS Double-Spring System:

The ERS system utilizes a Main and Tender spring concept that delivers optimal suspension balance. The Main spring (like this component) provides a linear-rate characteristic that determines the final rate of the system. When combined with a Tender spring, 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. This approach allows suspension engineers to achieve precise tuning that's soft enough to maintain tire contact over surface irregularities while remaining firm enough to control body roll, squat, and dive during aggressive driving.

Key Features:

• Linear-rate main spring for consistent, predictable suspension response
• Works with over 700 ERS components for virtually unlimited tuning combinations
• High spring travel and deflection capacity at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• High dynamic durability for extended component life in racing conditions
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection via phosphating and epoxy coating
• Clearly marked with part number, spring rate, and physical dimensions
• Compatible with Eibach connecting plates for Main/Tender spring configurations

Each spring is individually packaged for protection and easy identification. The ERS system's modular design allows racers and enthusiasts to adjust suspension characteristics for different tracks, conditions, or vehicle setup requirements without replacing the entire coilover assembly.
