KW Coilover Kit DDC ECU 08+ A4, S4 (8K/B8) 4Dr Quattro all engines w/o Electronic Dampening Control

This KW DDC ECU coilover kit includes KW INOX-LINE stainless steel struts with electronically adjustable dampers, an electronic damper control unit with a vehicle-specific cable set, and a KW DDC control button for in-cabin adjustments. It also comes with composite spring perches, elastomer bump stops with integrated dust protection, and detailed assembly instructions. This kit allows you to upgrade your 2009-2016 Audi A4 Quattro or S4 with an adaptive damper system that you can control electronically.

The DDC ECU system offers three distinct damper setups: Comfort, Sport, and Sport+. At the touch of a button, you can switch between these modes, instantly changing the adaptive damper settings to suit your driving conditions. Comfort mode is ideal for rough roads or when you need a smoother ride, automatically adjusting to sudden maneuvers. Sport mode is well-suited for highway driving and long curves, providing a balanced feel. For spirited driving on twisty roads with significant load changes, the Sport+ setting offers a highly sporty and performance-oriented experience, giving the car an unadulterated driving behavior.

KW builds these coilovers by hand at their headquarters in Germany, and each damper is individually tested on a dyno to ensure functionality and accuracy. The INOX-LINE stainless steel construction offers permanent corrosion resistance, and the composite spring perches prevent oxidation while maximizing strength. This means adjusting your ride height remains easy over time. For even more customization, an optional WLAN module can be added, allowing you to adjust the adaptive dampers independently per axle and even store or share custom presets via a smartphone app.
