I suppose I should specify how I checked it to see if I have made a mistake.

Using the ride height and taking the distance between the eyes on shock mount.
I used that distance as 0.
I figure these cars will have about 25mm bump.
so I went 50mm drop.
When I tested I went 50mm either side of ride height.

I mounted a plate to the wheel hub 6mm thick.
On the plate I marked a centre line at hub centre.
either side of that another line at 200mm.

(only had one gauge)
The dial gauge was placed on both of these outside lines.
The height of gauge was never changed when moved.
Using a jack the suspension was sent through its motion taking measurements at every 25mm.

The readings from the front & rear where subtracted to get the answer.
The difference was .120" (2.5mm).
That was one extreme to the other.
Over 25 bump & 50mm drop
I checked it over & over and kept coming up with the same answer so could only presume that this is correct and the mode of testing is ok.

After modifiying to links did exactly same test & the results are as my first post.

I just got to work and checked the a-d-c link positions.
Because the front lower link has been moved back to get to a good spot on the chassis it has put both C points outside the Line.
