Paul - I am not the best person to give you advice on setting up double arm shocks as my own experience of them was not good. I simply could not get any improvement on my A7 special's handling with a set of them and I reverted to standard setup - which is perfectly adequate for my use.
Yes, they are adjustable. In simple terms, the pivot bolt tightens against a star spring and exerts pressure on the frictions discs in the circular bit of the shock arm. The more you tighten, the more the resistance to the movement of the arm as the suspension gets compressed and released while you drive down the road.
If there is not enough pressure the suspension will bounce around and you will find the steering highly unpredictable. If there is too much pressure the suspension springing will not function well and be too stiff. You will then have poor steering because their is no compliance - the the wheels will be 'juddering' over bumps etc.
The happy medium is to find the point at which there is enough compliance but not too much - and you will get there by experimenting with tightening and loosening the pivot bolts. Try a turn or two of the nut each time, then take the car for a run.
If you want some idea of what I am trying to explain, tighten the nuts right up - go for a short drive. Then loosen them right off (not so far that they will unwind off the bolts and get lost) and do another short drive. You should notice a big diffence. Then start experimenting.
Have fun...!
