As I plan on improving the aerodynamics of my car I'm making a thread with my tests and modifications.
Maybe someone will find this interesting or usefull, maybe someone will have suggestions.

In my first test, I have use wool, tape and an action cam to visualize the flow on and around the rear window.
As you can see seperation is occuring in the center, but flow is staying attached to large portions of the rear window.
Therefore I'm going to mount vortex genertors near the center above the window to get flow attachment in the center section.
