I got this one

Saw it on a fellow members car and liked the look.
Useful thing about this one is the splitter is separate from the rest of the parts so you can decide just to fit that bit or with the "uprights" as is or have them painted then fit after. Just fits on with tape.
Look at my pictures and you'll get the idea.
I went matt black to match the rear diffuser, if you use wax car polish on matt it goes satin (though the genuine BMW diffuser looks more shiny satin that this).
Overall I'm very happy with the look for £75 and am waiting for "she who must be obeyed" to decide if she wants the other bits black, painted or not on at all. The under splitter bit that they include will not be getting fitted, a bit too chavy for my liking
