If the EBC info is correct, they are 23mm disc's not 22mm. Again, if all that info is correct, then the hat / bell section is 24mm.

Most manufactures list the Heigth as an overall height (Bell and disc) so take the 47mm height and subtract the 23mm disc thickness and 24 is the resulting height of the bell.

Something else that needs to be taken into account for is the thickness of the bell flange. The thickness of the flange will through the disc centerline off if it is not the same thickness as the original. Also, it can effect the offset of the wheel.
