Yooooooooooooooooooooooo!
I just thought of something that might make you crazy. Maybe even crazier than me.
If you want the COOLEST (IMO) and ULTRA RAREST mirrors that are similar to the MRacing you should try to find a pair of discontinued Phase Racing F1-style mirrors. Holy fucking sex, Batman!
They're since gone out of business in Japan and I've never come across a set but oh man if I could! Check 'em out. If you can't find any good pictures I'll see what I can pull out of old magazines and what not.
I can't believe I never thought of this until now. Oh! If you don't like them but find a set anyway, I'll take them! I'll throw you the MRacing in exchange plus whatever the cost difference is
