I have a 997 C2 and am planning to change the wheels.I am confused between the 19-inch Carrera Sport wheels as my car is in the GT Silver Metallic colour and the 19-inch SportDesign wheels.I also liked the 19-inch Carrera S wheels in Black...

Now my question is that which ones would suit best as I havent seen any of them personally and is it possible to purchase the 19-inch Carrera S wheels in Black from Porsche after the car has been purchased as those wheels arent in the Tequip section and are shown only in the Exclusive section...So what are my options?

 

I am not certain I totally understand your "confusion" between the Carrera Sport and the Sport Design wheels. You say you are confused, but.... exactly what are you confused about? Selecting a particular wheel style is mostly a matter of personal preference.

Here are some links which show each wheel.

Carrera Sport - 10 spoke, metallic gray is slightly darker color than most Porsche OEM wheels, but has polished lip
