That will have good effects on the camber curve
Ball joint even with or above the pivot. It still sweeps up but now moves in. That is a bad impact on the camber curve.  |
yes w. a normal down angle geometry on the A-arm track width varies
That and inherent roll steer are why as the suspension goes through its travel as you go down the road the wheel path looks like this
and yes the camber curve also varies a bit as shown here, in the top right diagram, sturtz is camber variation, up along the positive Y axis is bump, the camber curve in bump w/ stock geometry is almost vertical, meaning little variation w/ bump
Porsche built the car for the wider Porsche market, yes it's more focused and sporting than the wider market but it is still populated mainly by affluent Doctors, Lawyers and Indian Chiefs so many of the less sporting compromises were chosen, fewer in the specials like RS or CS or GT3.
That is why when a hardcore enthusiast gets one they immediately modify them to suit their idiosyncratic tastes
