Here is some info for you all on these:
Compatible pads listed below. It would be nice if a shop has the Rever stock pads, but not likely. The main thing is that unless they are 100% the stock OEM pads (shops usually do not have them) then you can use other compatible pads but not the "heat sink" insert (which is of questionable value anyway IMHO) because the backing plates of aftermarket pads will be teacher than the backing plate of the stock pads - making new pads+the heatsink too thick making it impossible to eliminate pads rubbing the rotor.
