The semi gloss is not gloss, nor matte. It just has a certain amount of sheen at angle. I agree, I don't like super flat black and really hate gloss black which just looks like a can of Krylon.
Well this poll was a big help. It's split 50/50 and so are the comments. LOL...
I just love how the RS barely shows itself. All you see are the calipers and rotors. That's just cool, especially with nice brakes.
The lighter colors look bigger. If you look at this page, middle of the page, where you see the faces of all three colors next to each other, the silver looks bigger, doesn't it?

Darker reduces diameter visually, but the reason I was considering it was my R wing, and my soon to be DF sport scoops are black. So it picks those up. I can always paint/powercoat my calipers body color. My idea was black R wing, Black sport scoops, black wheels. Silverstone calipers, new front DF lip with carbon center, painted sides. So from the front there is some black, from the sides there is some black.
I'm really confused. Arista thanks for posting all these pics, now I just have to keep staring at them.
