No shims included, had to use existing double shims from the old factory brake pads. Factory pads have spring clip riveted to hold pad in place, these have no clip, dont notice a difference other than a noise when I release brakes. When im stopped and take my foot off the brake pedal, there is a strange noise that was never there prior. The pads stop great, better than factory pads. No squeal, smooth, medium dust. Not sure I would buy again due to noise when releasing brakes.
