    Dominate The Track.

    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.
