The Eibach Pro-Kit has been designed to perform well in conjunction with Original Equipment Dampers as well as other aftermarket "Performance Dampers". Both of these dampers were designed around the original equipment springs and while they add a level of performance to the vehicle's suspension, additional performance can be obtained with a damper tuned specifically to match the characteristics of the Pro-Kit.
The engineers at Eibach based their development of the Pro-Damper solely around the unique characteristics of the Eibach Pro-Kit allowing the vehicle to take full advantage of the increased spring rate and vehicle's new lower center of gravity. The result is additional performance throughout the entire working range of the suspension.
The development starts with an "Aftermarket Sport Performance Damper" which is then tested and modified in conjunction with the manufacturer's proprietary components. Once the Eibach Engineers finalize their development, the new characteristics are incorporated into an exclusive production series by the original manufacturer.
