Z4 E89 AirRex V1 Air Ride Kit with Viair 444C, WiFi, 3-Gal Tank, Part No. AR-V1-Z4

For the Z4 E89 (2009-2016) - no M40i or sDrive35is exceptions, no N52/N54/N55 engine caveats, just bolt-on fitment across all variants.

• Pressure-based control, not time-based: maintains consistent ride height whether you’re loading the boot for a track day or dropping low for a show car pose.
• Includes Viair 444C compressor, 3-gallon moisture-separating tank, AirRex ECU + manifold, full braided plumbing, and touchscreen + WiFi module - zero add-ons needed for fast road or track day use.
• Monotube dampers with 12-click rebound adjustment: stiff enough for spirited driving, compliant enough for daily driver duty on UK B-roads.
