The Eibach ERS Platinum Rear Racing Spring is a precision-engineered motorsport spring designed for racers who require consistent suspension performance and dependable tuning control. Part number PR1800.500.0088 features an 88 lb/in spring rate and is developed for high-performance racing applications where repeatable handling characteristics are essential.

Built from high-tensile steel, this Eibach ERS spring combines low weight with excellent durability. Its flat-ground ends provide a parallel tolerance of plus or minus 1 degree, supporting proper spring seating and consistent suspension operation. The spring is also designed to provide more travel and deflection than standard racing coil springs, giving teams additional flexibility when optimizing chassis balance, grip, and ride-height behavior.

The Eibach ERS Platinum design maintains its dimensions and spring rate within exceptionally tight tolerances from lap to lap and race to race. Its block-resistant construction helps prevent loss of spring height under demanding conditions, preserving predictable setup characteristics over the service life of the spring. This individual rear motorsport spring is suitable for custom racing suspension setups and applications requiring precise spring-rate selection.
