FWIW, I've got no shims installed with my 100 pads and no noise while braking, not the slightest. Also, it seems to have worked just fine for me to have sanded down the pads slightly to make them fit. When I was done sanding, they were barely touching the rotor, and from what I've read and now experienced, this isn't a problem.
Good Luck
