Premium adjustable coilover suspension for BMW 1 Series F20 and F21 RWD without factory adaptive damping | KW DDC ECU | Part No. 39020019

Give your BMW 1er real-world agility, fast-road confidence and the perfect ride height with the KW DDC ECU coilover suspension kit. Designed specifically for rear wheel drive F20 and F21 models that do not have OE electronic dampers, including M135i and M140i, this package blends road comfort with tight body control and a purposeful drop for a true performance stance.

KW’s electronically controlled damping works with the supplied ECU to let you tailor the shock absorber behaviour to suit driving style and conditions. Paired with precision matched springs and stainless steel housings, the result is crisp turn-in, composed mid-corner support and refined compliance on daily journeys. We have installed this kit for multiple 1 Series owners and feedback has been outstanding for road and spirited B-road use.
