A question for other RMRacing pad users out there: How long did it take to fully bed the pads, and did the pads squeal?
I've used a bunch of sets of those pads and like them a lot. My usage is primarily on the track. For track usage, you need to break them in in order to keep them from wearing out too quickly. To break them in, you need to get them very hot, then let them cool down - for example, with a whole bunch of VERY hard 80-20 mph stops at 1-mile intervals on a deserted highway. Normal street usage won't give them the heat cycling they need.
If you're only going to use them on the street, then you probably don't need to worry about it. They should work fine and bed into the rotor pretty quickly.
I have never had a set of these squeal, on the street OR on the track. I'm pretty good during the pad change procedure about using anti-squeal goop on the back of the pads and cleaning out the places where the caliper holds them.
