That wing is a colossal piece of shit. My car in the US still has one and the only reason it's still on my car is because the previous owner stored it in a garage it's whole life.

Now that my rant is over, I can tell you you'd be better off keeping the car wingless. Fill the holes and repaint the trunk. Best thing you can do for the longevity of everything below the hatch.
