That would be great greystoke.
I actually took some measurements the other day.

On the wheel itself:
From the wheel mounting flange to the opening (where the chrome boss cap snaps in) is 2-5/8" tall.

The rotor center hub height is 2" tall with the dust cap removed.
(these are auto parts 5-lug rotors purchased locally)

At the end of the rotor hub (where the dust cap presses on) the diameter is approximately 2.800". This is using my cheap plastic dial calipers that I have at home.

The diameter of the opening of the wheel (where the center hub dust cap sticks thru) is only 2.410".

If you could measure your Baer rotors center hub "height" (minus the dust cap),... and a diameter of the center hub, (right at the base of the dust cap),... that would be great!
