Bilstein has long been known for its inverted tube technology that allows the piston rod to be installed at the bottom of the shock tube body. And it is exactly what the company used for the Bilstein Pro-Kit, resulting in increased torsional strength for better handling and control. Eibach, on the other hand, takes pride in its wide range of lowering springs designed to lower any car´s center of gravity, squat during acceleration, body roll in corners, and excessive nose-dive during braking. When these two are combined in one complete package, you get aggressive good looks and high-performance handling without compromising safety or ride quality. The Bilstein Pro-Kit offers lowering between 25 and 40 millimeters depending on the application, and it’s made following strict OE standards for a direct fit and functionality.
