Or go with this color combo I attached OR even ferric gray powder coat.

Now, in my personal opinion you should keep these wheels for when you sell the car as they look absolutely fine as they are, and buy yourself a nice 20in set and go a bit more agressive. I would suggest the 20in from the M550D, the 434 style in dark gray. Remember, you got 19s, they will look even smaller in black color. So perhaps if you dont like that polished look go all silver or gray color like in pic I attached. Also dress up the calipers.

I think non msport car with black 19in plastidipped rims has a risk of looking on the cheap side of things, but that's just me. ICKDEEP above has a nice looking car thanks in part to the great color and Msport being accentuated by it, so rims look good there, even in 19s (and the M351s look bigger than 19 due to that design).
