Eibach 0800.250.0325 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Main Spring is engineered to deliver precise suspension tuning for racing and high-performance applications. This linear-rate coilover spring serves as the primary spring component in Eibach's renowned double-spring system, providing the foundation for optimized vehicle dynamics on track and street.

ERS Double-Spring System:

This Main Spring works in conjunction with Eibach Tender or Helper springs to create a sophisticated dual-rate suspension setup. 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 design delivers superior balance between compliance over surface irregularities and firm body control during aggressive cornering, acceleration, and braking.

Key Features:

• Linear-rate characteristic determines the final spring rate of the system
• 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 tolerances for consistent performance
• Block resistance design prevents coil binding
• Part number imprinted on spring indicates rate and dimensions for easy identification
• Individual protective packaging ensures quality during shipping
• Compatible with over 700 ERS components for virtually unlimited tuning combinations

Designed for use with Eibach Connecting Plates to attach Tender springs, and suitable for professional race teams and enthusiast tuners seeking precise suspension control. Each spring is manufactured to exacting standards with high dynamic durability for long service life under demanding racing conditions.
