Product Details

KW DDC ECU Coilovers

KW Dynamic Damping Control ECU
Individuality by the push of a button.
The KW DDC coilovers are part of the KW iSuspension program - the intelligent suspension solution. They combine the advantages of an adaptive damping system with a vehicle-specific aftermarket suspension solution. They're offered in two versions: KW DDC ECU with the option of using KW's App control and as, KW DDC Plug & Play for selected vehicle models with factory adaptive suspension.

The adaptive KW DDC ECU coilovers allow adjustment within the tested lowering range. The dirt-resistant trapezoid thread and the composite collar allow years of accessible adjustability and ease of use. Lowering can be done via the composite spring collar on the shock body or on the height adjustable rear perch in the rear of the vehicle. No matter where in the world, sporty drivers, car manufacturers and refiners rely on our KW technology _''_''Made in Germany_''_''.

Each KW coilover kit is produced at our headquarter located in Fichtenberg, Germany. During the production process each kit is subjected to extensive stress tests and must meet the high quality standards set by KW management and surpass OEM quality. Over 4600 applications come supported with a multi-year warranty. Currently KW DDC ECU coilovers with App-control are available for Audi, BMW, Mercedes-Benz, Porsche, Volkswagen and Range Rover Evoque.
