Ordered new Mazda rotors (TD13-33-25X). Only one hole for the set screw and it doesn't line up with either hole. Seems odd. I realize they are not necessary. I had two screws in my 2010 GT factory rotors. (Was able to get both out using a $5.49 manual impact screwdriver found at the local auto parts store -- piece of junk but got the first two screws free).
The new rotors look like this: http://parts.arlingtonmazda.com/products/PLATE,DISC-(TD13%2d33%2d25X).html
Also much greater outer pad wear (less than 1mm on outer pads, ~3mm on inner pads). My lower caliper pin was a bear to pull out, so I'm guessing the caliper was not releasing fully?
72K miles on these first set of OE pads/rotors.
