Rear suspension is non-adjustable. There are kits available to make them adjustable, but it's a weld-in, and pretty complex/lot of work. I've done one. It uses the eccentric bolts and washers from a 5 series.
Some 6ers had automatic air-adjust suspensions. They eventually fail and everyone converts them to springs.
Well, I'm off toward Mobile to make the rounds of insurance, tag and alignment. Report to follow.
