I don't know how much it helps or hurts but I made these mirrors out of styrofoam for my 94 protege:
(I have a piece of clear tape over the broken edge of the homemade plexi rain guard transitioning from the top of the mirror. Not on the picuture)
For size comparison to what came off:
It took about a week to get used to them but after that I was able to use them in traffic like a normal mirror.
I also don't drive with my arm over the door/ elbow stuck out the window anymore because as soon as the tip of my elbow makes it past the window channel, it's in "high speed" airflow which is an instant reminder to roll the window at least half way up. (no a/c in Florida weather ).
(..you know you're an ecomodder when you run the window up with the heater on in Florida so you can keep the grill block and take advantage of the aero mirrors...
)
I actually have a thread on them:
