Product Description

The Eibach 2072.140 Pro-Kit is a set of four progressive-rate lowering springs engineered specifically for the 2001-2006 BMW E46 M3 in Coupe and Convertible body styles. Dropping the front approximately 0.6 inches and rear approximately 0.9 inches, the Pro-Kit closes the fender gap left by the factory suspension while lowering the center of gravity for improved traction under acceleration, reduced body roll in corners, and shorter stopping distances under braking. The progressive spring rate design -- 27 N/mm front and a 66-132 N/mm progressive rear -- allows the springs to feel supple and compliant during everyday driving while building resistance progressively as suspension loads increase, maintaining ride quality without the harshness associated with linear high-rate springs. Every Pro-Kit spring set is engineered using Eibach's proprietary spring design process and tested by both suspension engineers and performance driving professionals at Eibach's facility in Corona, California. The kit is designed for use with factory OEM dampers and installs without modification, though pairing with performance dampers is recommended on high-mileage vehicles to avoid accelerating shock wear. The 2072.140 is also a component of Eibach's PRO-PLUS and PRO-SYSTEM-PLUS upgrade packages, making it compatible as a starting point for a full Eibach suspension build. Drop heights are approximate and vary based on vehicle condition, current ride height, and load. This kit is backed by Eibach's 5-year warranty against factory defects in materials and workmanship.
