If I'm not mistaken if you opt for the carbon fiber sport design package, the look would be identical to a Turbo S with the sport design option. If you opt for the exterior color or gloss black sport design kit the standard black plastic lower lip will remain without the add on.
4S - Black Plastic Lower Lip
Turbo - Body Color Lower Lip
Turbo S - Carbon Fiber Lower Lip
Oh yes, you are right, sorry. Didn't catch that you are talking about the carbon version. Indeed, the carbon sport package on a 4S looks exactly the same as on a Turbo or Turbo S.
