I believe that purpose of that front lip is to generate "virtual" optimum nose shape. So that makes the nose virtually round if you add there a spline which goes over the highest points of the bumber. Most of air will go through that route. This is my scenario which worked pretty fine on one car actually cd were calculated by computer at valmet.
