you basicaly need a rear subframe bolting or welding in, then you can use some lightweight alloy hubs of your choice, and conect them with tubular wisbones. quite simple fab rear but not really worth it unless your racing or something.

i know about camber gain, but on a track car with almost no rear suspension movement, it will be a very small amount you could dial in, and you see very little camber loss in a rear beam for the same reason, i doubt you would see any benefit in lap time in a fwd car, fun if you had an unlimited testing budget though!

It will still be pivoted badly, so when you turn a corner, camber will still become more positive.
The factory rear beams axis of rotation is transverse, not longitudinal, therefore the camber would not become more positive on the rear under cornering, it would remain constant.
Clearly you don't know what you are talking about because it does, if you turn a left hand corner the rear right becomes more positive as the car rolls, since the car rolls to the right the wheel will be pointing in towards the left (positive).

Here is my design for a 205 GTI one, running Mcpherson struts, maybe I will design one for a corsa B have been thinking this for a while.
thats abit overally complicated cause if you look a 205 beam for years people tap a bigger thread in the ARB, take the torsion bars out and drill and tap holes in the arms to take coilover units and turret the rear, current set up i've seen in a quite a few hill climb cars.
If I think I know what you mean, it will still have a rear beam but with upright springs/dampers but still not independant.

Rear beams have a very low roll centre height compared to the front so it understeers, mine has basically the front suspension on the back so having nearly the same roll centre heights, so massively reducing understeer and giving the car more of a predicable 4 wheel drift handling.
