Eibach - RACE SPRING SYSTEM | ERS

Motorsport Springs & Accessories - RACE SPRING SYSTEM | ERS

Essential Part of the Pro-Plus & Pro-System-Plus

It was in Germany in the 1980’s when Wilfried Eibach engineered the first designs of today’s legendary Eibach Race Springs.We still have saved a “Typenliste”, just one sheet of paper, from the year 1986, which pictures the first 50 ERS part-numbers, all metric, 60 mm ID – inner diameter.Obviously this basic approach was spot-on, as even today these historical part-numbers are part of our complete Eibach Race Spring System though a few differences have to be recognized. The quantity of part-numbers/single components have grown from 50 to over 1,300 while early designs are consistently being improved in line with superior materials and manufacturing technology.

The ERS line has evolved over the years to be the world’s most prominent, comprehensive and superior Race Spring System. Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.

In an instance when an application cannot be covered by the Eibach Race Spring System, then Eibach offers a bespoke design and manufacture service.

Based on decades of experience, Eibach has optimized their products to realize the lowest weight and smallest solid height – therefore increasing the maximum travel, block stability, linearity of the load/deflection graph, sag stability and dynamic durability.

Suspension Tuning with ERS

Every suspension tuning is a compromise! Early in a racer’s career, they are confronted with the challenges of Over- or Understeer.

On one hand, the spring system should be compliant and soft enough to compensate for bumpy roads or tracks. This compliance assures permanent road-contact of wheel and tire and therefore guarantees grip and traction.

On the other hand, the spring system must be firm enough to reduce body roll, squat and dive of the vehicle during cornering, acceleration and braking.

Thus, we offer an endless variety of spring combinations utilizing our ERS System:

  • 2 (or even 3) ERS Springs with different rates are stacked, resulting in a progressive spring-system
  • various options are possible in serial hook-up
  • 2 or 3 different main springs – one after another
  • 1 main spring with a tender spring (a linear or progressive one)
  • 2 different main springs plus a tender spring (a linear or progressive one)
  • similar options are available in parallel hook-up

Our ERS System offers the Race Engineer multiple set-up options. This has made Eibach the leading brand in Motorsport springs everywhere around the world.

  • Over 1,300 single components – main and tender springs – metric and standard, various auxiliary race suspension accessories, ready and in stock on 5 continents
  • Comprehensive Program of single components
  • Single Main Springs with highest rate-linearity and lowest rate tolerance
  • Progressive Characteristics via set-up of different springs serially – double or even triple spring combinations
  • Extreme Low Weights achieved through Super Hi-Ten materials and manufacturing technology
  • Smallest Solid heights, maximized spring travels and higher maximum loads
  • Spring Surface Stabilization through specialized shot peening
  • Every ERS Spring preset to block
  • Block and Sag Resistant
  • Smallest Tolerances and precise plane parallelism of spring ends
  • High Dynamic Durability – under Motorsport conditions
  • High quality corrosion protection by phosphating and epoxy coating
  • Springs Printed with part-number (which translates = Length, Inner Diameter, Rate)

EIBACH DOUBLE-SPRING SYSTEM EIBACH DOUBLE-SPRING SYSTEM

EIBACH 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 SPRING SYSTEM EIBACH MAIN AND TENDER SPRING SYSTEM

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 EIBACH MAIN AND HELPER SYSTEM

EIBACH MAIN AND HELPER SPRING 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.
