After enjoying the safety enhancement of the EDM aspheric mirrors on my "genwon" BK Mazda3, it was quite intolerable driving the BM Mazda3 with huge blind spots and poor rear visibility. Visibility is what I miss from the "genwon"
Once you knew about the existence of something better, you just can't take anything less! As they say, "ignorance is bliss"! And yes, I did adjust my mirrors "properly"... the driver side (flat) glass was as outward as practically possible, but having to deal with the little "port hole" of a back window and the inside mirror to cover the further distances just sucked!
Costing a small fortune, I imported a pair of mirror glass from Germany. Really, the passenger side glass isn't really necessary because the USDM glass is also convex, except the EDM one has no silly warning label. I just chanced upon one on German ebay for "cheap", so...
To me, you can't put a price on safety... This is "cheap insurance" that all the gadgets the car with can't always help you (BSM, rear cross traffic alert, and rear camera). IT IS WORTH THE MONEY!
I don't have "before" pics here, because I couldn't wait to install these as soon as they arrived from Germany after dark a few days ago. But since if you're reading this thread, you probably have a 3rd gen Mazda3 anyway. You can certainly refer to my two previous threads of my other cars, of course.
But, this pic should really show how much improved rearward visibility is. There's now zero blind spots when you are parallel to another car/traffic, and greatly reduced if you're at an angle.
The angle is so wide, I can adjust the mirror to both cover a bit of the side of the car (great for parking) and it still reflects the outer portion of the housing!
Installation is not quite as easy as it used to be with the older Mazdas. The mirrors are a frameless design. They are glued onto the plastic bracket/backer which means you have to be extra careful removing the original glass. The shop manual says to heat up the mirror with a hair dryer for both removal and installation, which is a good idea because the sockets are very tight fitting compared to the "genwon" (BK) and "genpu" (BL) ones. I believe this is by design as an anti-theft measure for some countries where mirror theft is high (such as Mexico). Even when heated up, removal and installation is not very easy as considerable amount of force is needed to pop these in/out, which can be a bit scary!
For those interested in importing these (contact an importer/exporter, I can't help you), glass only part numbers:

All "driver's side" mirrors are aspheric. All "passenger side" mirrors are regular convex without warning labels. To get aspheric mirrors for both sides, order a LHD and RHD driver side glass.
For example: GHR5-69-1G7 (LHD driver/left side), and GKM1-69-1G1 (RHD driver/right side)
Reference:
LHD driver side = left side
LHD passenger side = right side
RHD driver side = right side
RHD passenger side = left side
WARNING: These mirrors do not comply with FMVSS/CMVSS 111 (US and Canada rules) and ADR 14 (Australian rules) and are technically illegal in these countries. Use at your own risk! They are fully compliant with UNECE r46 and JIS D 5705. These are fully legal in most countries where UN vehicle regulations are in effect or allowed.
