SINGLE BEST SAFETY MOD I HAVE DONE ON MY 2020 RT. Completely solved the shaky mirror issue that Can Am seems to be unwilling to address. Took about 45 minutes to do both mirrors. Looks like just hardware store bolts, but the little squares are what you are really paying for. Trying to fabricate a set of squares yourself, finding the exact right length and size of bolts, etc. is just too time consuming. These guys have done all the "engineering", fabricating and sourcing for you. There are videos on how to remove the mirrors without damaging them. Game changer for rear view riding vision. Best price on the internet.
