Fitted the front wings yesterday morning and the car looks ever more like a car.  I asked my wife to come to the garage to look at it, I think she thinks I'm barking mad.  It is clear that the shroud is out of shape though, on the near side it is quite distorted around the headlight opening; I'm very surprised that I didn't notice this earlier.  I will fit the rear wings now and see how the door gaps are, that will be fun.
