Here's how the Brabus front & rear spoilers look installed and painted black, and having the impact strip also smoothed out and painted black. Bumpers cost about $675/each, and need to be prepped and painted (about $370/each).
I haven't taken a picture yet, but I installed Hella driving lights in the spoiler recess, with "city lights".
Enjoy.
