no no, not talking about the rotors edge-width.......I'm talking about the pad-sweep surface.....it's about 1-1/2" wide......nothing out of the ordinary- many aftermarket rotors come in two styles- one that will work with factory calipers (big pads/ 2 pistons) and one that works with most aftermarket calipers (small pads/4-6 pistons). The one I've got is the narrow/aftermarket caliper style.
