Just a quick calculation on what a mirror delete could potentially net me:

Assuming a roughly 1 square foot reduction in frontal area, and a Cd drop of 0.01, the aerodynamic improvement could approach 7%. Without the Cd drop, it is nearly 4%. Here's to hoping reality matches theory . .

I've already installed one of these mirrors inside the driver door and I like it so far. It has a very firm but easy to change adjustment setup, but more importantly to me is that it is actually glass with minimal distortion. (Which I can only regrettably confirm since the 2nd one arrived broken!)

I can certainly see a much wider area with it if not directly below the rear quarter panel, but I am not concerned with that blind spot with the rear view camera covering a lot of what I will lose while backing up. I think it fits in relatively well too without all of the complication and expense of doing outboard cameras.
