Are Mazda 6 and MS6 rear brakes the same?

I'm about to do my first brake job on my MS6, and like with many other pieces of this car, I'm having trouble finding information about the parts I need. Specifically, in my search for brake pads, I have been struggling to find rear brake pads that confirm fitment for the MS6. Most brands seem to only have front brakes for the MS6 but no rear brake options; the only rear brake options are for a regular 6. I couldn't find a straight answer online if the pads would be interchangeable, so I was hoping someone here would be able to give me a more concrete answer.

Also, on the same interchangeability topic, is the Mazda 6 suspension (specifically the control arms) the same as the MS6?

 

If in doubt check Mazda part numbers online
