I think the stripes will look good on carbon black and really stand out. Here is another X6 with the stripes in a different pattern.

I doubt the bumper will fit without lots of other pieces since the fog lights, etc moved around. I'm showing my '11 X5 M Sport. The X6 is somewhat different than the X5 as well.
