Product details
The Airtech Air Suspension kit for the 1999-2005 BMW M3 in E46 form includes two front and two rear air struts, with 36-way damping and adjustable lower mounts. The height range runs from 0 to 120 or 200 mm depending on the vehicle, which gives a wide window for setting the stance.
Air management is not included. The struts work with most air management systems, so you can pair them with a controller and compressor of your choice, or move up to a complete KSport system for this car. A tool kit with spanner wrenches, damping knobs and brake line brackets is supplied.
The 3 Series from 1999 to 2005 in E46 chassis, including the 323i, 325i, 328i and 330i models and their Ci variants, is also listed. Professional installation is recommended, and the OEM top mounts may need modifying on some applications. Re-check the air-line fittings once the car has covered 500 miles or a month has passed.
Supported features
Designed for easy bolt-on installation and compatible with most air management systems on the market.
Near-infinite ride height adjustability from the air spring plus 36 levels of damping adjustment on each strut.
Crafted from high-quality metals and rubber compounds, proven to handle daily driving and track use, with superior resistance to road contaminants.
Fine-tune ride height at any pressure through the adjustable lower mount.
