Air bag suspension on my 18 legacy?

[WisconsinKyle]

I have been slowly adding stuff to my 18 legacy. My main complaint is that when i pull into a parking spot or leave my driveway i hear my front bumper grind on the ground. I either have to park far away in the parking lot or drive sideways out of the driveway. I was hoping i could add something that would allow me to raise and lower  my car as i please. I know you can get coil over suspensions that allow you to manually adjust the height of the car by getting out and turning a wrench, but i would like to be able to make these adjustments from inside the car. Raising up an inch or two be enough. I just dont know enough about air bags to make an informed decision. Any information on this would be helpful. Thanks.
