Front valence air dam/splitter
Have you noticed in the press kit pics that the yellow C6Z has a little black "lip" under the front valence air dam? And have you noticed that most all recent pics of the C6Z that I've seen (the ones from the car carrier, the super large pics of the red one, etc) do not have that piece?
Was is removed/scrubbed? I would like to see that piece there in the production car. I'm sure it will get scraped up quick on driveways and the like, but it's probably a rather easy piece to replace (price and "do-it-yourself") and that is provides a positive effect on air flow into the main intake duct opening as well as downforce by more effectively "splitting" the air flow.
