Every Eibach Pro-Kit is designed and tested by our suspension engineers and performance driving professionals, to deliver aggressive good looks and high performance handling, without ever compromising safety or ride quality.
By using our proprietary, progressive spring design, Pro-Kit provides the ultimate balance to take your passion for driving to a whole new level."
