About KW DDC

KW DDC coilovers have electronically adjustable dampers, so the factory adaptive-damping features stay usable while KW's stainless-steel INOX-LINE struts handle the lowering and ride-height adjustment.

DDC ECU version: the kit adds an electronic control unit with a vehicle-specific cable set and a DDC control button, with three vehicle-specific damper modes (Comfort, Sport and Sport+). KW also offers an optional DDC WLAN module for app control; it is not part of this listing.

KW builds its coilovers by hand at its headquarters in Fichtenberg, Germany. Each one carries an individual serial number, and KW says every damper is dyno tested before it ships. KW develops vehicle-specific damper and spring setups on the Nürburgring Nordschleife and in its own 7-post test center.
