Plug-and-Play Electronic Coilovers Built for BMW’s Factory Suspension Brain
The Bilstein EVO SE coilover kit (BIL49-305135) is a direct-fit, height-adjustable suspension system engineered specifically for BMW G20/G21 3 Series and related xDrive models equipped with factory electronic damper control. Unlike conventional coilovers that force you to disconnect the OE electronic suspension, EVO SE integrates directly with the factory EDC and Adaptive M Suspension systems, so drive mode switching and adaptive damping continue to function exactly as intended. Designed and tuned in Germany on the Nurburgring, this kit lowers the car up to 70mm while sharpening handling and preserving daily comfort.
