Hello Heinz,
A very very interesting topic which I shared with members of the Roadster 100 Register, drawing out one comment from a member with unsatisfactory steering on his Roadster..
As a result I have published a Technical Blog Page for our Register Members which also now includes my own observations, photos and understandings.
Here is the link to that Blog Page, which I hope the content is acceptable to you.
