I've noticed that for the last couple of years the wings flare out slightly.by which I mean the top of the wheelarches aren't parallel with the road . it's easy to see on the lower wing leading edge...it goes up as it goes outwards. Most noticeable on the 4/4 for some reason. It gives the car a tiny amount of agression in it's stance, which suits the narrowness I think.

Good spot - definitely flare out having looked again at the photos - I think the wider Plus 4 wing might also flare out but I think because the 4/4 is narrower it accentuates it more and gives it extra attitude like a cat with its paws out catching it's prey
