D2 Racing D-BM-70-ART Air Strut Kit BMW 3-Series F30 & 4-Series F32 RWD

The D2 Racing D-BM-70-ART is a complete front and rear air strut kit engineered for the 2012–2018 BMW 3-Series (F30, RWD) and 2014–2020 BMW 4-Series (F32, RWD) with 3 and 5-bolt front upper mounts (FUM). These vehicle-specific air struts are a direct replacement for factory suspension components, delivering a dramatic improvement in ride height adjustability and damping performance over stock.

Each air strut features dual-path height adjustment — through both the adjustable threaded lower mount and the inflatable air bag — providing an exceptional range of ride height control. Air bag style (sleeve or double bellow) is matched to the OEM suspension design of your specific application. Adjusting air pressure directly controls ride compliance: higher PSI firms up the suspension, while lower PSI softens it for a more comfortable feel.

Key Features:

• 36-way damping adjustment — dial in ride quality from comfort to performance using the included damping knob (turn clockwise to stiffen, counterclockwise to soften)
• Dual ride height adjustment — adjustable lower mount combined with inflatable air bag for maximum height range
• High-pressure air bags — engineered and matched to your vehicle's OEM suspension geometry
• Sleeve or double-bellow bag design — application-specific based on factory suspension type
• Direct bolt-on fitment — designed for 3 and 5-bolt front upper mount configurations (RWD only)
• Compatible with any air management system — manual, electronic, Bluetooth app, or preset-based control (sold separately)
