That's fine--but if you want to
know if the smaller blindspot mirror (with or without fairing) has lower drag than the stock mirror, you will need to test it. There's an unfortunate belief on this forum that you can assess the aerodynamics of an object or shape simply by looking at it when this is
not true, especially when it comes to small add-ons subject to interference drag in areas with complicated flow patterns such as mirrors. (You'll find statements to this effect in any textbook on aerodynamics; I know because I've read a lot of them!
You can--and should--too).
