Right.... my findings today....

Using a 4x4 anti roll bar seems to help a lot. It pushes the hubs out a little wider with the TCA's. I did however have to re-drill the holes in the cross member so that the TCA's could bolt to it as I did not have enough movement there.

Cambered the wheels nicely.....
Pushed them out at the bottom bu about an inch,
This has given an extra few degree's on the steering.
Re-tracked it and away we go.......

It seems to have worked..... only time will tell!
