A little more toe-in will improve straight-ahead responsiveness. I'm talking roughly 1 mm at a time circumferential rotation at each of the two tie rod adjustments.
: Can anybody tell me what is adjustable on the E34's front suspension?
: The steering on my 540i is unpleasantly vague when driving along a straight road (and, yes, I've removed the play that the steering box can induce). I believe classic suspension theory would suggest that there is insufficient castor, but castor angles are rarely adjustable.
: Can castor be adjusted, and, if not, what's the likely cause of vague straight-line steering?
