What about the mirror arm cf covers? WHo makes those? R u happy with them?I was coming to show him a pic but I see OP already handled it. Oh well, I'm already here with a pic ready to go.
This is where I got them.

They're not real carbon fiber like the mirror covers or the triangles. These are plastic with a CF finish to them. They don't look bad, and they fit well, but they don't cover the whole arm of the mirror and I only realized when I got them. I'm ok with them. Wouldn't buy them again but also not throwing them out.
