The brakes are the same for all lines & packages for their respective markets & engine sizes. Cars with M-sport package (option 337) have the same brakes as standard as on other trim levels within the same engine size, only if option 2NH is ordered with option 337 then u'll get M-sport brakes. Without option 2NH the brakes are not called "M-sport brakes", regardless of whether option 337 (M-sport package) is specified, hence so far M-sport brakes does not exist for US-spec cars w/M-sport package.
