It's the first place I tried but they're the dumbest of all.
They don't even know what it means to have a friction code.

I always reasoned the dealer is the dumbest of the parts stores.
Because nobody ever asks them for a "parts choice".
They only have one part. The OEM part.
The friction code isn't something they even THINK about.
So they're clueless.

I tried to explain it to them but they asked "why do you care"?

If they can't figure out why a cold & hot friction code matters for
friction materials that have only one job, cold and hot friction, then I
can't help them learn as they're too stupid to learn if they don't know the
most basic of the simplest thing.

There's NOTHING more important for friction material.
And yet they don't even know what I'm asking of them.

I asked if they could just show me as I can read the friction code right
off the correct part, but they didn't want to order it just so that I could
look t it.

Parts stores will show me the parts, where I can read the friction code
right off the part, but I wouldn't know if it's the OEM friction code.

As for rotors, I'm pretty sure they all work exactly the same.
