KW Coilover Kit DDC ECU BMW M3 (E93) Conv. w/o EDC

KW is known for making high-performance suspension systems, and their DDC ECU coilover kit for your 2008-2013 BMW M3 Convertible is a prime example of their engineering. This kit lets you upgrade your M3 with an electronically adjustable damper system, giving you control over your car's ride performance and comfort right from the driver's seat. It’s designed to integrate seamlessly with your vehicle, offering a way to tune your suspension for everything from daily driving on rough roads to spirited runs on twisty routes.

What makes this kit stand out is the intelligent DDC ECU (Electronic Control Unit) that works with the coilover suspension. You get three distinct damper setups: Comfort, Sport, and a more aggressive Sport+ mode. These settings can be changed in milliseconds via a button in your cabin, adapting the suspension to the road conditions and your driving style. The coilovers themselves are built with KW's INOX-LINE stainless steel, which means they are highly resistant to corrosion and built to last. The spring perches are made from a durable, low-friction polyamide composite that prevents oxidation, ensuring easy ride height adjustments over time. Each damper is individually tested at KW's German headquarters to ensure it meets their strict standards before it ever ships out.

This kit includes the KW DDC ECU coilover suspension with stainless steel struts, the electronic control unit with a vehicle-specific wiring harness, and a control button for your interior. Installation is made easier with the included detailed assembly instructions. For even more customization, an optional W-LAN module can be added, allowing you to fine-tune settings via a smartphone app and even save or share your custom presets. This system is designed for M3 models that do not have the factory EDC (Electronic Damper Control).
