Hi Hermie,

Vortex generators add drag and they add (a little) frontal area. You can try them -- I would do tuft testing, but my guess is that you will either notice a slight loss of FE or have no change. I very much doubt if you will gain anything in the handling department. Any wing that adds downforce will also add drag -- or you might just get the drag and no added downforce.
