When the configurator first came on line, I clicked back and forth between the CF options and non-CF options. I zoomed in the best I could and it sure looked like the CF was just replacement for the black plastic bits and the exact same shape (the configurator has been updated to show the different shapes now). Like most carbon fiber stuff on cars, I figured it was actually heavier than what it replaced and just showier, so I passed. It actually worked out in the end as I will (hopefully) get my car sooner than if I had optioned it.
