Hi Wynand,
I think the work you have achieved without the "book" is very impressive indeed, to work from plans only available on the "net", which having looked at the said drawings sometimes don,t give vital info, the result of your construction is to be highly commended
I,m not a suspension set-up expert, but may I say the one thing that caught my eye was the angle of the steering rack outer arm position appears quite extreme, thats not said in a negative way, as I,m just comparing it to the position in the "Book" for the Roadster, do you have adjustment of the actual steering rack main body where its clamped to the chassis to lessen the extreme angle? just a thought.
Look forward to seeing more photos of your build
cheers
