Default Some questions about adjustable suspension arms (for camber)

Vehicle: Ka 1999 T reg, 195/50/15s, used for autosolos, track days etc
I have 2 sets of knacked wish bones (bushes worn) so I am thinking to remove the ball joints (rivetted on just now) extend them and slot out the holes so I can bolt the ball joints back on and have adjustable camber. A few questions have popped up though:
1) Is there a way of calculating how much camber in degrees I would get per mm of movement on the lower ball joint? I can do it on paper but its physically getting the measurements off the car I am strugling with.
2) With a drop of 30mm (on 30% stiffer springs) how far can I let my drive shafts extend by?
3) Any other sugestions for adjustable front camber? Thought about concentric/shift plate top mounts but Im running full size springs, plus I was advised against them (although I cant remember why right now).

Why not just get some adjustable tca's made ?, pm me if you want some.
If you take accurate measurements of the location points distance wise the angle can be calculated exactly.

Because I like playing with grinders and welders :P Do you mean threaded pipe and rose joint style? (okay I know it's a bit more intricate than that!) I was concidering basically welding a similar setup on to the wish bone and then thought modifying the way the original ball joint is mounted would be easier.

At the moment the car is my daily runner too, until I get a replacement so I can start on the shell work etc. Im finding it difficult to measure up into the turret acurately with the strut assy in place. Also the springs on there just now are no where near the shape they should be. And the shocks are knacked. Infact the whole suspension is shot. Happy days.
