mirriors any one have theses

My buddy bought a used busa with similar mirrors but in chrome ... no use in having a mirror if they shake so much you can't see what they're showing you ... My best advice: Stick with stock, the real thing, not a copy (there is a difference)
I have those mirrors and insert LED strips in the hollow part as turn signals, been using them now for 2yrs. I love mines, it doesn't shake they have allen screws to make them as tight as u want. No problems with mine. So times the installer can cause unwanted problems but mines are good. Got them from Ebay, they have plenty of colors to choose from.
