Need help figuring out what rotors I bought!
Hello I bought two brand new rotors today and when ever I search the part number all I get are Russian sites but don't list what exact motor they are for! The part number is N3Y3-11-B10A. I'm starting to think they are RE rotors as the rx8, fd, and fc part numbers are all different from this one. Thanks!

I'm guessing one of the numbers didn't stamp nicely, specifically the N3** part.
Take a pic for ***** and giggles for us if you like. Is the rotor valley cast or machined?

I'm interested in this as well. I've just taken my first engine apart and it's a rebuilt engine. Not sure what the builder used, so I want to verify for myself.
Will the valley on one type be smooth vs the valley on another type be rough/textured? I'm assuming cast = rough and machined = smooth? I may be completely wrong...who knows!

I bought them out of Japan, there brand new so I have a pic of the Mazda sticker with part number so its the right one. From the pics you cant really tell if its smooth or not but it doesent quite look like the s4 rotor I have.

my Ukrainian parts catalog is down right now, because they have been invaded, but i did happen to notice that in the USA the S4 turbo rotors are an N3Y2-10-B10A, and are all magically a C weight, but in the JDM parts catalog they listed the B and D weight rotors as well, and the part numbers were N3Y1 and N3Y3....
