Air Lift Performance rear air suspension kit for the 2015-2018 BMW M3 (F80) and 2015-2020 M4 (F82). It uses a divorced setup with progressive-rate sleeve air springs mounted separately from high-performance monotube, threaded-body shocks that offer 32 levels of damping adjustment and threaded lower mounts. Braided stainless-steel leader hoses feed the springs, and the kit lowers the rear up to 4.4" (112mm) below stock without sacrificing ride quality.
