My new 2012 Mazda 3 (Skyactiv) with Air Lift V2 management (1/4" lines) and AirREX suspension. Just showing the range of height from (mostly) all up, to all down. You can hear the air compressor running a bit in the background, although it is quite loud inside the car. Also I think 1/4" lines make the car raise quickly enough, no need for 3/8" lines.
