It looks as though they are attached with double sided "badge" tape which providing they follow the same sort of contour as a MK7.5 should be a doddle to fit as no drilling or anything like that is necessary.
Where do those go?They aren't on my car... are they an optional mud flap type part?Are you in Ireland?
Oh hang on, those are the "winglets" for Mk8's with factory 19's.I have those on my Mk8 GTI.They are just a tiny extension used to get around that the 235 tyres project wider than the wheel arches.... which is illegal without them.
PS I joked about Ireland because you guys over there seem obcessed with mud flaps
