I just installed the ExtendView Side Mirrors made by Really Light Stuff ExtendViewâ„¢ Side Mirrors | Really Light Stuff I bought the "blue glass" anti-glare version. A tremendous improvement over the stock mirrors, which I think are inadequate particularly given the limited rear quarter visibility of the Roadster body design. I searched the forums but didn't find any posts about these particular mirrors. They are rather unusual because the outer third (almost, but more than one quarter) of the glass is quite convex and lets you see objects directly adjacent to you and across over two lanes to either side. And at the same time you can see almost to the edge of the Roadster body so there is a lot of overlap between the ExtendView mirrors and the rear view mirror. I quickly became so confident in the wide field of view offered by these mirrors that I had no need to turn my head to check before making a lane change, I just signal, glance at the mirror, and if it's clear change lanes while keeping my eyes looking ahead. Searching the forums for "side mirrors" led me to believe that the "Multivex" side mirror that has been posted about the past is no longer available. The ExtendView Side Mirrors made by Really Light Stuff seem like the best choice out there. They fit very well into the existing mirror enclosure, and come with four round, thin, adhesive pads per mirror. The pads are too large to use whole, I cut them in half and placed the curved part close to each corner leaving about 1/16" of space as the instructions recommended. Here's a photo showing how curved the mirrors are.
