2018 mazda 6 turbo front brake rotors smaller than 2019 model?

Hello, I've been doing a little research on the brakes for my 2018 Mazda 6 Grand Touring Reserve and I'm hoping someone can help answer my question. It seems that the front brake rotors on my 2018 Mazda 6 GTR are 297mm. I've noticed that the front brake rotor size on the 2019 & up Mazda 6 GTR is 320mm. I have also noticed that the calipers for the 2018 and 2019+ model 6 are listed as the exact same part number. The pictures of the calipers look identical as far as the brackets go. If anyone can confirm that the 320mm front brake rotors from the 2019 Mazda 6 GTR will fit my 2018 Mazda 6 GTR without changing the brake caliper I would really appreciate it before I go buy rotors and find out for myself. I've also seen the CX-9 brake upgrade available for my car but I'm hoping to just be able to use the 2019 Mazda 6 GTR rotors as they are supposed to be bigger without the need for swapping calipers and brackets. Any help to answer my question will be greatly appreciated, thank you.
