I kinda googled this a bit but couldn't seem to find an answer to this. What I am thinking of is using aftermarket coilover air suspension, then possibly hooking to factory air lines/ compressor? Instead of using aftermarket compressor/ tank/ management since the car has this already. I am no expert on air suspension and I don't need it to air out to be on the floor. But this could possibly give us access to many more air shock options with customization on dampening while maintaining oem standard height and high height functions.
