MB1,
I think don't the black wheels will compliment the Cyber Gray very well. I love the carbon fiber although my future combo will be Velocity Yellow with Black Wheels and Carbon Fiber. I think if you went with a gray or "smoked out" wheels the carbon fiber would fit more into place and give it a racier look. If you are going for a more classy look then I would leave the carbon fiber off and keep the car Cyber Gray all the way through. Either way it is a great color!
As far as the yellow goes there are great pictures that are not washed out. The combo is awesome! I have seen it in person and without a doubt it is a racer!
