Had a question regarding 'airing out'. When I lower my car (MK5 Jetta) to park I probably lower to about 30 PSI all the way around (enough to tuck wheels for style). I know a lot of people get these Air lift kits to complete air out to 0 PSI, but my question is what does it take other than pushing a button to safely 'air out'. I am not running an aggressive wheel setup as it is pretty close to stock (17x7 et45| 225/45/17). Is it recommended for fender rolling/pulling to do a 0 PSI air out without having to worry about rubbing?
