There are many coil over spring manufacturers but Eibach stands out as a leader. Eibach has been producing linear coil over springs for nearly 40 years and have become the spring supplier to some of the world's greatest factory racing teams and programs. They have achieved worldwide recognition thanks to their high quality standards, spring rate consistency, and a wide variety of rates and lengths. BimmerWorld has recognized Eibach's quality over the years and it is now the official spring for our IMSA race team and other various motorsport projects, as well as our own street vehicles.

Eibach ERS race springs are made with high grade tensile steel for superior strength and weight savings - critical considerations for race use. Their spring designs achieve maximum travel with the smallest block heights and their spring rate consistency is what keeps suspension engineers insisting on Eibach ERS springs. Springs are manufactured either in Germany or California and each spring is individually tested and block set.

The Eibach 2.25" (57.15mm) race springs listed here are known as "main springs" and they are the primary springs in a coil over suspension. They are available in several lengths and rates using the imperial system (inches and pounds). Metric rates and conversions are also available, please inquire. 2.5" springs are also available (see link below). Tender or helper springs are also available depending on your setup and suspension tuning goals.

For example, a common BMW 60mm race spring is 120/120 so the closest Eibach imperial spring is 5.0"/700lb (with 7mm more height).
