Tony, those do look sharp!
Additionally, the OEM CX-3 discs are suspect. According to (U.S.) TSB 04-002/17, "Some vehicles may exhibit a squeak[ing] noise when applying the brakes and/or groove marks (A) on the front disc plates. This is caused by abrasive metal from the front disc plate sticking to the brake pad, which damages the disc plate over time." I'm still waiting for my dealer to replace mine.
Check out this rotor from an Official JDM Mazda site touting a special version of the CX-3. Notice the groove at about 9:30 ... looks like that would tear-up any pad, in short order!
P.S. The Anchorman is a brake expert ... 'wonder what he thinks :-)
