Projectnmt :
Thinking about your set up question again, in practical terms, I think it really depends upon by how much you are raising the ride height over the set up you would like to use, but at 5mm.
Let's say you are raising from 4mm to 5mm, I would try the following if it was me (and I'm open to contradiction from more experienced racers here) :-
1) raise the ride height by 1mm - what you need to do
2) increase the amount of wishbone drop (i.e. arms hang lower when car off the floor) by 1mm - maintains the droop setting
3) shim the camber link under the ball stud at the hub end by, say, 0.5mm - keeps the distance from the centre of gravity to the roll centre similar
4) see if it drives the same and if not try something else!
Best of luck
