Eibach 0500.200.1100 ERS Race Main Coilover Spring

The Eibach 0500.200.1100 is a precision-engineered Race Main Spring designed for the company's renowned ERS (Eibach Race Spring) double-spring system. This high-performance coilover spring transforms engine power into optimal track adhesion through precisely balanced suspension tuning that reduces body roll, squat, and dive during aggressive driving.

ERS Double-Spring System:

This Main spring works as part of Eibach's innovative ERS system, which combines Main and Tender springs to create a sophisticated two-stage rate design. The linear-rate Main spring determines the final spring rate of the system, while Tender springs (sold separately) establish the initial softer rate. When both springs compress together, the system provides a compliant initial response for road irregularities, then transitions to a firmer rate once the Tender spring fully compresses—delivering the perfect balance between compliance and control.

Key Features:

• Linear-rate characteristic provides consistent, predictable spring behavior
• Compatible with over 700 ERS components for virtually unlimited suspension tuning combinations
• 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 manufactured to tight tolerances for consistent performance
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Block resistance design prevents coil bind
• Individually packaged for protection during shipping and storage

Designed for serious racers and suspension tuners, this Race Main Spring is part of a modular system that allows precise suspension setup through the strategic combination of Main, Tender, and Helper springs with Eibach connecting plates. The result is a suspension system that can be fine-tuned to match specific track conditions, driving styles, and vehicle requirements.
