As we learned, to change a stage 1 Z06 to a state 2 only requires the carbon fiber aero package. Also we know you have a "painted carbon flash black carbon fiber" option (CFZ) @ $2,995, or a "visible carbon fiber" aero package option (CFV) @ $3,995.
Yesterday, Chief Z06 Designer Kirk Bennion confirmed that regardless of which of those two preceding options you select, the spoiler is always black. In fact, every Z06 factory spoiler, stages 1 through Z07, is always black!
Though slightly off subject, confirmed while at BGAP, that option TTV, the painting of the door mirrors, remains an option, i.e, saw a VY Z06 with its black mirrors going down the line. Z06 option TTV is the same $100.
