exactly what are you refering to? do you mean clearencing the seals, or the rotors themselfs.

I think theres only 2-3 places in the world that clearence the actual rotor. and as for how its done... hours and hours a machining research and a bunch of money.

see the faint circle around the outside of the oil seal grooves? that's the step the clearancing leaves.

and yes all the 13b rotors made after the rx8 came out are clearanced from the factory
