josiahg52: Hub bore is 72.6 and I have 20mm plates that have the smaller hub on the outside. This results in a bit too much width in the back but it is only for a week or two until I can sort out the 212s that will go with the car.
BMT: I just coded out the LD and exercised the air suspension in INPA. I have put up a few pictures of the screens.
Once you get to the second screen hit "Activate" and the next screen has the controls to lift and drop either both sides simultaneous or one side at a time. Pretty straight forward.
