I have read a lot of sedan kammback builds, most of them using newer, more rounded cars. So I need your help on this one.
I have mocked up this cardboard kammback.
However, I think that it could turn out to have a negative result because the air 'overshoots' the trunk.
Without kammback there is lots of turbulence in the middle of the rear screen, but some reattached air on the spoiler.
The kammback can't be much longer, because then the trunk will hit it.
What do you think?
- Would the car benefit from the kammback?
- Should I leave it alone?
- Or should I make the spoiler on the trunk longer, so flow can reattach?
