White all day long. I like the carbon effect but it needs to be on a darker colour base to work properly IMO else from behind unless you're close up it looks like someone's hit the car and you couldn't find the right colour replacement panel lol
I like the black, gives more to the car, can look a little bland in all white. No offence, I have a white 2 and the centre panel is white. Seeing yours considering going for carbon panel more.
