I just received mine in the mail today, but they look like they were a used piece or something because they had this yellow Evo-R sticker:
I definitely did not want this yellow sticker on my Pearl White Z because it did not match with anything on it....my attempt to take the sticker off resulted in this:
I definitely would like a partial refund or something for this problem. No one should have to buy these mirrors, receive them with a yellow sticker which is only on one side, have to take it off and then be left with a messed up paint job which I will have to correct.
Other than that, I have no other problems with these mirrors. I don't have a scale so I don't have the exact weight measurements, but I can definitely say that these are not heavier than the originals, but are not a dramatic weight saving piece. If you want to lighten your car, there are much more effective ways than changing mirrors.
Install was simple and took less than an hour for both sides.
Take out these three screws/bolts and then just pull/pop the door panel off.
With the door panel out of the way, you can just pop the plastic triangle piece from the inside/backside of the mirror, unplug the mirror, take off the three nuts holding the mirror, and then remove it.
At this point, you'll want to clean up the black residue from the bottom of where the stock mirror was. If you clean it good enough you can choose to use the black sticker which is provided to cover up that spot or not.
After that, then you can place the new mirror in and screw the three screws in. Be careful putting these screws in and do not force them when turning/screwing them in. The metal is soft and can the threads can be stripped if you're not careful.
If yours doesn't come with the sticker, then you don't have to repaint/repair the paint damage from peeling the sticker off :P Just need to adjust the mirrors and tighten them down. Hope this helps people a little.
