KW Coilover Kit DDC ECU 07+ 3-Series E91/E93 2WD Convertible

The composite spring perch, made from wear-resistant, friction-optimized polyamide with a stainless steel insert, is a smart design choice. This combination prevents oxidation that can happen with standard perches, while the stainless steel insert ensures it stays strong. This means adjusting your ride height will be much easier over time, even after years of exposure to the elements.

This KW DDC ECU coilover system brings intelligent, app-controlled suspension tuning right to your BMW 3 Series E91/E93. It combines ride height adjustability with electronically controlled dampers, allowing you to tailor your car's performance or comfort on the fly. You get a vehicle-specific set of cables, a control button for easy access to different modes, and KW's high-quality Inox-Line stainless steel struts for true permanent corrosion resistance. Each damper is hand-built and individually tested in Germany to ensure accuracy and functionality.

With this kit, you can select between three distinct damper setups: Comfort mode for rougher roads or daily driving, a balanced Sport mode for highway cruising and general performance, and a very sporty Sport+ mode for spirited driving on twisty roads. These settings change the adaptive damper settings within milliseconds, giving you an unadulterated driving experience when you want it. If you want even more control, an optional DDC WLAN module lets you fine-tune settings independently per axle and even use a smartphone app to save and share custom presets.
