The Air Lift Performance rear kit is an adjustable air-suspension lowering system for the 2019-2024 BMW G20 platform - 3-Series, 4-Series, 2-Series Gran Coupe and Z4. It uses progressive-rate double-bellows air springs to lower the car while retaining ride quality, and air pressure is fully adjustable so the car can air up for clearance and air down for an aggressive stance. Backed by a one-year unlimited-mileage warranty.
