Eibach 0700.225.0700 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) system represents a precision-engineered solution for race and performance suspension tuning. This race main spring is part of Eibach's renowned double-spring system, which allows suspension engineers and performance enthusiasts to create nearly unlimited spring combinations from over 700 different components.

ERS Double-Spring System:

The ERS system utilizes a Main and Tender spring concept that delivers sophisticated spring rate characteristics. When both springs compress together, the system provides a softer initial rate for superior road compliance and grip. Once the tender spring fully compresses, the main spring's firmer rate takes over, controlling body roll, squat, and dive during aggressive driving. This race main spring features a linear-rate characteristic and determines the final rate of your suspension system.

Key Features:

• Linear-rate main spring design for predictable suspension behavior
• Compatible with Eibach's modular ERS system for custom spring rate combinations
• High spring travel and deflection capability at compact mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component life
• Precision manufacturing with tight tolerances
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions
• Individual protective packaging to prevent damage

Designed for use with connecting plates to attach tender springs, and compatible with helper springs to prevent spring unseating at full droop. This main spring provides the foundation for a precisely tuned racing suspension system that balances compliance with control.
