Eibach Race Spring-System
EIBACH DOUBLE-SPRING SYSTEM
Suspension tuning is a precise balance. On one hand, the spring system should be soft enough to absorb track irregularities assuring maximum adhesion, while on the other hand the spring system must be firm enough to reduce the body roll, squat, and dive of the vehicle during cornering, acceleration and braking. For optimum balance, Eibach has developed the ERS double-spring system. By combining Eibach Main, Tender and/or Helper springs, the suspension engineer or weekend racer can create the perfect combination of spring rates for the ultimate suspension set-up. With our extensive range of motorsport spring sizes and rates—our ERS double-spring system is unsurpassed in performance and flexibility. For Off-Road racing where extreme wheel travel is a must—combining two different rate main springs gives you the softer rate required for small bumps and a stiffer final rate to prevent bottoming on the bigger bumps and jumps.
EIBACH MAIN AND TENDER SYSTEM
The Eibach Main and Tender spring concept provides a softer initial rate when both springs are compressed together, then delivers the desired firmer final rate once the tender spring closes completely. The Main spring has a linear-rate characteristic and determines the final rate of the system. The Tender springs are available in linear or progressive-rate (shown) and determine the initial rate of the spring-system.
EIBACH MAIN AND HELPER SYSTEM
A Helper spring is used to prevent the Main spring from becoming loose in the spring seat when the suspension is unloaded or at full droop. The Helper spring, unlike the Tender spring, has very little spring rate, and therefore has no effect on the suspension characteristics of the vehicle. Up to 2" (50mm) of spring-to-perch gap can be covered with the use of a Helper spring.
