Hi, I have an imported 2008 370 GT (coupe) Skyline with the smallest 307mm rear brakes (as far as I can tell, didn't have time to take a wheel off to measure properly). I’ve tried looking for replacement rotors, but I always end up with part number 43206-JK600 (such as here: https://www.amayama.com/en/part/nissan/43206jk600), which is for the 330mm rotors. Or did the base coupe always come with 330mm rotors?

Does anyone know the OEM part number for the 307mm rear rotors? I obviously can’t fit the bigger ones without changing calipers.
