Hi Paul,
Well as you say nothing too onerous to sort out there.
Guess it's a little disappointing but you already know it should be a breeze when you go back.
We've often said on here that certain issues are open to interpretation by different inspectors but sounds like you have had a decent guy there who alas could not pass due to straightforward stuff and you've accepted it quite correctly that way.
I'm no expert but I think it will be Caster angle on the front you need to change. Adjust the trailing link length. Maybe your bottom ball joint is wrong and you are not getting enough articulation in the joint to get enough Caster?
As I said I'm no expert and preferred to leave initial set up on Frederics Corse to Blink Motorsport, only a mile from my workshop. I have a print out of the settings they achieved so will try and post a picture up for you shortly.
Has worked pretty well on initial road use.
