Now an update on this.
After a while on google and youtube, it seems like the flares would fit after all. Even original, they look like they're just retrofitted on top of the original wheel arch trim. Well.. That's not how I thought it would look from factory...
Example here:

I haven't decided yet, if I want to fit them like the original ones are fitted, or if I want to fit them to look like I thought they were supposed to be. If I go for number two, it would involve a great deal of irreversible work.
