I found some pictures for a painted bumper, the color seems abit different from the body color. It appears that the painted bumper is abit dull.

I painted my bumpers, and sides about 6 months ago, still good as new, as long as they prep the bumpers and prime them good, the paint will stick no problem, as for the aero kit, I just got the front bumper for about $500 instead of the whole kit

where to get that front aero for $500? I am out of source here in canada.

you will need:
51-11-0-306-061 front bumper
63-17-6-910-791 right fog lamp
63-17-6-910-792 left fog lamp
51-11-0-305-015 right bracket
51-11-0-305-016 left bracket

I paid $627.71 usd for all those parts, my dealer gave me a discount, good luck!!

What are those # stand for? BMW parts #?

yes, those are BMW part numbers, your dealer should be able to look them up even in Canada
