All brembo kits come with Ferodo pads as far as I know. They are great pads (obviously), though the dust kinda annoys me. That's the price you pay for top-notch performance, though, and it's not like your OEM pads don't produce a TON of dust anyways.
You can replace with Ferodos and just about any other pad. Because Brembo is the OEM choice of AMG, Ferrari, Lamborghini, Porsche, etc, all the pad manufacturers make sizes for their kits in my experience.
We sell replacement pads to our customers all the time when they track their Brembo kits.
Especially the 6 piston kits - those have been OE for all AMG cars for quite a while now, so everyone makes them.
Probably why nobody has commented
Let me know if you have any other questions
