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.

I put new tires on yesterday and looked closer at the rears and over half the pad still remains, just like the fronts. Thats top notch in my book. The only other brakes i had last like this, were on my 1990 Talon TSi AWD, i got 30k+ out of them delivering pizza. Now, thats not near the abuse i put on this car, but its the only other metric i have to go up against personally.
That would be the Z23 pads :)
Aside from that, prob the CX-9 calipers and rotors. eBay or for used ones.
Agree - I am running z23 pads on cx9 calipers on my 6. And that was the cheapest upgrade even after I had to transport it to Europe fm US :)
