The Eibach ERS Platinum rear racing spring is designed for motorsport applications that demand consistent handling, precise tuning, and dependable performance under repeated high-load conditions. This individual Eibach Motorsport spring uses high-tensile steel construction to provide a lightweight solution for optimizing suspension response across a wide range of race vehicles.

Engineered to maintain its dimensions and spring rate within exceptionally tight tolerances, the ERS Platinum spring helps preserve predictable suspension behavior lap after lap and race after race. Its flat-ground end configuration supports consistent seating, while the block-resistant design helps prevent permanent loss of spring height. The spring also provides greater travel and deflection than standard racing coil springs, giving suspension tuners additional flexibility when balancing grip, compliance, and chassis control.

This Eibach spring is rated at 112 pounds per inch and is intended for use as a rear suspension component in applications requiring precise spring-rate selection. It is supplied individually, making it suitable for custom race-car setups, replacement needs, and suspension development programs.
