Montegue,
Yes I agree with you re. the 90' orientation required on the upper mount. How much better would the shock's last/perform if the rotational elements were in the same plain rather than trying to bend the shock absorber longitudinally. Should have realised you might have already addressed the vertical orientation to reduce rotational forces though. Silly me!
I have Spax adjustable shocks as supplied by SSL on the rear of my car and Rog's assisters. Went for the SSL option as I knew they would have the correct open/closed length, and I find that to be as good as I can get with the standard set up. If buying now I would go with Cain's new to the market shock's. I can't remember how many clicks up from softest setting I have but seem to remember that it's about half way, There really is a sweet spot which seems to-jump out at you when you hit the right setting for your car, I found that easier to find stepping up from softest setting rather than dropping down from the hardest setting as stepping up you can easily identify that click up that changes it whereas dropping down you notice a change right through the middle third of the range and I found it difficult to know where to stop adjusting but on going up it was obvious. I have about 34mm static unloaded spacing between the adjusted assisters and top of the leaf spring with the car on the ground and it really has made a huge difference in ride quality. The contact mark on the top of the spring is about the size of a 1P coin so I figure I'm only just using the helpers in slowing that final level of compression to the springs.
