It is springs only: the factory dampers stay in the car, and each spring perch is adjustable so you can set the drop precisely instead of accepting whatever a fixed lowering spring gives you.\u003c\/p\u003e\n\u003cp\u003eThe reason it exists is the electronics. On an adaptive-damper M car, replacing the dampers means dealing with the EDC circuit — either a bundled coilover kit with cancellation modules, or fault codes. H.A.S. sidesteps that entirely. Because the OE dampers and their sensors are untouched, no ESC or EDC cancellation module is required and the car sets no damper faults. Drive-mode damper control keeps working exactly as it did.\u003c\/p\u003e\n\u003cp\u003eThis is the kit for an owner who wants the stance and the reduced center of gravity without giving up the factory adaptive damping or its warranty story. If you want adjustable damping as well, look at the V4 coilover kits for the same chassis instead.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHeight adjustable springs only — the factory adaptive dampers are retained\u003c\/li\u003e\n\u003cli\u003eContinuously height adjustable\u003c\/li\u003e\n\u003cli\u003eNo EDC \/ ESC cancellation module required; no damper fault codes are set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFront and rear KW height adjustable springs with adjustable perches\u003c\/li\u003e\n\u003cli\u003eMounting hardware and KW's fitting instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNothing electronic is required.
