Yea that is where I bought the adapter from. $59 in shipping. Taking one for the team. They also didn't have a 380mm adapter listed so I reached out to them and they added it to the site.
MC should be just fine since the normal G-series use up to a 395mm huge rotor and caliper with the same MC.

Did some more research with the full fat M six piston calipers. On the M G8X the rotors are 380mm and fit under 18" wheels. The base G8X comes with 18's in the front.
