Why air on this car

The BMW 3 Series E90 M3 is the saloon version of the generation’s V8 M3, built for family duties through the week and track days at weekends. Its flared arches sit close over staggered wheels, and lowering it on fixed coilovers usually means the front lip catches every driveway before the stance looks right.

Air suspension changes that trade-off: you can set a low preset for parking or a show, lift it for speed bumps and multi-storey ramps, and still have enough compliance left for a fast road drive, rather than the harshness of a coilover set hard and low.

This car left the factory with electronically adjustable dampers, so the kit comes with a cancellation kit stopping the dash reading a fault once they are removed; the original adaptive damping is not retained. The front mount is rubber, keeping road noise low, with a pillowball or pillowball-rubber option for sharper steering feel. Simpler tiers keep the cost down; upper tiers add corner-by-corner and height-sensor control with presets.

What's in the kit

Struts and bags

Struts and bags is the air suspension hardware without any management: four vehicle-specific struts with 36 levels of damping adjustment and the air bags that go on them. Choose it if you already run management you want to keep, or you are buying the RC1 or RC2 controller and tank separately.

Who it suits: Owners keeping their existing management or choosing their own, who need only the struts and air bags.

  • No tank, compressor, valves, remote or wiring included
  • For existing management or separately chosen RC1/RC2

Fitment notes

  • Front top mount: Rubber top mount. The standard fitment on McPherson-strut cars. Rubber isolates the body from the strut for the quietest ride, at the cost of a little precision. Camber is not adjustable on this mount.
  • Rear top mount: OE top mount. The kit reuses your car's original top mount rather than supplying a new one. Ride feel and camber stay as the factory set them.
  • A pillowball front top mount (camber adjustable) is available as an optional upgrade — there is a surcharge for changing the standard top-mount setting. Ask us when ordering.
  • Your car has electronic (adaptive) dampers. This kit is supplied with the matching electronic damping cancellation kit, which takes the place of the original dampers on the wiring so the car’s damping control system is satisfied.
  • Listed by the factory as: 3 SERIES E90 M3 (Cancellation Kit for Electronic Damping).
  • Built to order — the typical lead time is around 21 working days from the date of purchase to UK delivery. We confirm the lead time for your kit before you pay.

Five years against oil leaks, with a service every two years

AirForce covers its air suspension struts against oil leakage for five years. To keep that cover, the struts need to come back for inspection and maintenance every two years; the manufacturer treats the service as a condition of the warranty, so book it in and keep the paperwork.

Damage caused by suspension components rubbing against an inflated air bag is not covered, which is why we ask your fitter to cycle the system to full height and check clearances before they hand the car back.

Compressors, air bags and the electronic control box and remotes carry the manufacturer’s separate terms, and electronic parts may need to go back to the factory for repair. Ask us for the current wording before you order.

None of this affects your statutory rights as a UK consumer. If a product is faulty, your rights under the Consumer Rights Act 2015 apply alongside the manufacturer’s warranty, and your contract is with us as the retailer.
