I've heard a couple other people complain about how bad the stock mirrors vibrate at higher speeds. Mine would vibrate so bad at 55mph+ that all I could see in them would be a big blur. A few days ago, I took a couple large sized (18") Nite Ize rubber cargo ties, and wrapped one around each mirror stem. Today I rode with them for the first time and they probably reduced my mirror vibration by 60% or better. I could see cars behind me in my mirrors at 65mph no problem, although if I used 2 of these per mirror it would probably work even better. Here's a link to what I'm talking about: New Authentic Nite Ize Gear Reusable 18" Rubber Twist Tie Blue GT18 2pk 03 | eBay I see these for sale in a lot of places. It's a good cheap, easily removable solution.
