KW DDC ECU Coilover Kit For BMW M3 (E90/E92) Sedan/Coupe w/ EDC

The KW Dynamic Dampening Control (DDC) coilover kit gives you all the control you could ever want. With a click of a button you get individual lowering and three different damper setups. It can be chosen between a basic setup for sporty driving on normal roads, a comfortable setup for un-even/poor road surfaces and the extra sporty setup for maximum driving dynamics on well maintained roads and race tracks. The different damper settings are controlled electronically with a proportional valve that regulates the flow of oil in the damper within milliseconds of you hitting the button.
