Explosive acceleration. Sharp, responsive handling. Featherlight, carbon fiber components. But what about that ride height? With Air Lift Performance, you can easily take your BMW M4 from that stock, street car look, to a sleek and low 'ultimate driving machine', all with the touch of a button. With Air Lift Performance, there's no worrying about bottoming out on speed bumps, scraping your undercarriage, or going up driveways. Our engineers made sure that your M3/M4 will perform at its absolute best, both on the track and on the street. Our engineers dropped the BMW M4 4.4in, giving it exactly what our air suspensions are famous for -- the maximum drop. But getting it low was not enough for Air Lift Performance. The kits we build are also about providing a level of versatility that common coilovers cannot achieve. That means eliminating the classic lowered-car problems, like bottoming out, by providing the maximum amount of adjustability with ease. Every M4 kit we build not only provides your Bimmer with a show-stopping stance, but also maintains a great ride and handles the curves like a performance monster should. The BMW M4 rear kit features a similar formula to the front kit -- threaded, height-adjustable dampers paired with double-bellow air springs. The dampers feature 30 levels of adjustability, creating an air suspension that is completely customizable for your ideal performance setup. As the leader in air suspension products for more than 70 years, Air Lift Company and its Performance division is committed to delivering quality parts that fit, work and last. To ensure the highest quality, longevity, and customer satisfaction, the key suspension components have all been torture-tested to 1 million cycles on our in-house hydraulic test rig at temperatures ranging from -30 F to 150 F.
