The Eibach replacement front coil spring for BMW 3-Series sedan (2006–2011, E90; 325i/328i/330i) restores front ride height and improves suspension consistency after wear. Eibach forms selected spring steels on precision CNC winders, applies heat treatment and shot peening, then finishes with a corrosion-resistant powder coat for long service life. Each spring is set to block to help maintain the correct ride height over time.
