This 2000 E39 540 is aging well (150K +) but I think what it needs are springs. I had the original shocks replaced at 120K with the Bilstein HDs. I guess these are fine but the ride height increased after they were installed. Consequently, the alignment cannot be perfected - there is a slight undesirable negative camber in the front. I am considering some H&R springs to drop the overall height which would have the intended effect of looking nicer and allowing for some more aggressive camber in the front and possibly a more level rear end. Is it worth considering new (different) shocks at this time as well? Any experience out there with this kind of modification? I've had thrust arm bushings recently done with some heavy duty part from Bavarian Auto. They seem to be a good improvement over the stock piece.
