KW Mercedes C63 AMG Black Series W204 DDC ECU Coilover Kit

This KW DDC ECU coilover kit includes KW INOX-LINE stainless steel struts with electronically adjustable dampers, a high-performance electronic control unit with a vehicle-specific wiring harness, and a KW DDC control button for in-cabin adjustments. It also comes with an elaborate set of assembly instructions to help with installation. This system allows you to upgrade your 2012 Mercedes-Benz C63 AMG Black Series with an adaptive damper system, giving you control over your vehicle's performance or comfort settings.

The KW DDC ECU suspension offers three distinct damper setups: a basic Sport setting, a more aggressive Sport+ setup for performance driving, and a Comfort mode for everyday use. You can switch between these modes with the touch of a button, and the adaptive dampers adjust within milliseconds to suit the selected mode. The Sport+ mode is ideal for spirited driving on winding roads, while Sport mode is suited for highway cruising. Comfort mode is designed for less-than-perfect road surfaces and automatically adjusts to sudden maneuvers. The composite spring perches are made from a wear-resistant, friction-optimized polyamide with a stainless-steel insert, preventing oxidation and maximizing strength. The INOX-LINE stainless steel construction ensures permanent corrosion resistance, meaning the coatings won't wear off during ride height adjustments, giving the coilover struts an unlimited lifespan.

Each KW DDC ECU coilover kit is hand-built at KW's headquarters in Fichtenberg, Germany, and receives a unique serial number. Every damper is dyno-tested before release to ensure functionality and accuracy. For even more customization, an optional DDC WLAN module can be added, allowing you to adjust dampers independently per axle and tailor them to your personal driving style and conditions via a smartphone or tablet app. The elastomer bump stops include an integrated dust protection system to prevent water and dirt from reaching the piston rod and seals, acting as dynamic load limiters while maintaining ride quality.
