Damn, I have an 01 with only rear bags. I was hoping to change the front to bags and use the compressor to raise - drop the vehicle at will. Could it be done? Would there be lines in the car already or would I have to run them from the boot. Would it be best to speak to a suspension expert and maybe get a bagged system controller installed where I could overrun the self leveling system, and control the bags entirely from a remote?
