At MJ Modifications we have installed and used this AirREX kit on customer cars and our own demonstrators. Feedback has been consistently positive on comfort, handling, usability and reliability. If you want your BMW to go low without sacrificing drivability, this is the upgrade we recommend.

V2 height-referenced management

The V2 control system monitors suspension position with dedicated height sensors, so you save and recall true ride heights rather than chasing air pressure. Set it, store it and the car returns to your chosen height accurately. Rise On Start gets you to a practical driving height as soon as you turn the key. Use the wireless touchscreen for quick adjustments or control everything from the companion app on your phone.

Performance air struts engineered to fit

Each strut assembly is designed as a direct replacement for the OEM units. Air springs are load and pressure tested, then paired with correctly valved monotube shocks for balanced response and stability on real UK roads.

• Front: 12-click damping adjustable monotube dampers, camber plates where applicable, threaded bodies, bellowed air springs
