I have a bottle of Snake Oil that's designed to make the suspension work much better that I'm happy to lend to you. It will facilitate rotating the eccentrics at the bottom of the rear upright such that you can set both toe and camber.
The eccentrics do that anyway, but happy to help a fellow owner...
If anyone from AST or MCS would care to explain their thinking on this matter I would be happy to listen and publicliy accept that I'm wrong. Merry Christmas.
