I want to put the M Sport rear onto my car, I have the bumper and trim piece, but I am confused on the diffuser. What color is the diffuser supposed to be? I’ve seen it as gloss black on lighter colored cars, but my 335 is black sapphire metallic. I’ve seen many black 335s with the diffuser looking unpainted, but I’m confused now as to what color it is supposed to be. Thanks in advance.

From BMW they are a satin metallic silver color

I’d advise you not to go gloss.

Either black matte or satin is the way to go. I personally went with a black satin look on mine.

I had a spare for my E60 that I painted satin black. My car is titanium silver metallic. I also had a 128i M Sport, the color on that diffuser was a bit more grey, but it was also more of a satin finish. That car was Alpine white. I'd say choose a color somewhere between black and dark grey, and paint it with a satin finish. If you're having a body shop do it, they'll do a normal base/clear and just add a matting agent to the clear coat.

I had mine painted satin black.

I think gloss black would look good.

I have a glossy carbon fibre one now.

Sometimes contrast works. 07 Black Sapphire here. I had the body shop match it to my Advan RS' in Dark Gunmetal Metallic. Sh!tty phone pic at night, but you get the idea.

My pre-lci AW came with a matte black diffuser. And like you, I've seen them in matte, satin and gloss..

I have a Tiag so I went with satin black.

Yea mine was satin silver when I bought it from the dealer for my m sport conversion.

Flat or matte colours on the exterior look cheap and look dirty.

Plasti dip is a good example, turns to crap and looks faded, so why put something thats already flat onto the exterior.

Gloss, clear coated is the way to go.

just had the dealer paint my LCI alpine white m-sport rear and they did the valence in space gray metallic and it looked exactly how my factory one was. It is definitely in the gunmetal gray family. Matte or unpainted looks unfinished IMO.
