The problem as I see it, is that the Honda rim sits on the hat section
of the brake rotor, and using spacers would in fact just be used to fill
the space between the rotor and the backside of the rim. This would
prevent bending of the rim around the lug openings, and reduce the
possibility of tearing out the holes. As for the 2 mm spacing
difference, Hondas use much larger studs, and so there is some room for
adjustment, but you are correct in recommending larger studs, both in
diameter and length, so this play might disappear.Thank you for your
comments, I will use them in making a decision, as it sounds like you
have had some experience in this matter before.
