Hi,
camber:
problem with camber recommendations is ride height and also wheel/tyre dimensions / width and shock absorber stiffness and sway bar stiffness. And in the end hardness of the tyre edge and tyre pressure. So maybe it works on one car but not on the other. Also it depends on your driving style. A versatile racing driver adjusts his way to drive on the car and might be also fast in a car that someone else thinks has too much understeer or is undrivable. So … best way is to try different things yourself.
sway bar:
In general it's as i dsecribed. I know that the US Porsche guys tell you it's the opposite way. There are some factors like weight distribution and weight center that can affect the feeling. But just think about what the task of a spring a shock absorber and a sway bar is.
A spring is responsible for the ride height.
A shock absorber dampens shock – rebound and compression stage.
A sway bar connects the left and the right wheel. If for example (in a perfect world) the right wheel is pushed down, because you corner the car left, the sway bar pushes the left wheel up, so the chassis stays straight and both tyres have the maximum contact area.
If the sway bar is soft, the car will wank more.
If the sway bar is stiff, the car will wank less and will have more traction.
But there are a lot of factors that can affect that. Depends on how the chassis is designed, how stiff springs and dampers are …
