M3/M4’s with standard brakes are the ones with the wrong booster. Even though the N55 M2 and M3/M4 share standard brakes, N55M2 uses CCB brake booster.

that's interesting

so given the M2 N55 uses M3/4 brake hardware, is the brake booster even that important

as someone with a ceramic retrofit kit to fit, i might try them on road before dealing with the hassle of swapping the booster out
