Sorry to put an old post back up, but I wanted to thank everyone for their input into my problem.
As stated earlier info is at a premium in this country, and even Honda plus some of their dealerships were unable/unwilling to help me with my probs.
On another note, it would appear (have not purchased as of yet) that the MC18 and MC21 front ends are compatible ie easily interchangeable, even though the wheels are different specs.
Looks like I will be updating my front wheel to the MC21 spec (rotors attached - just to replace one brake rotor) because it is cheaper - not to mention easier - in this country to do it this way.
Anyways thanks again everybody for your insightful help.
Regards,
Matthew
