I began installing this kit yesterday and have come to the point where although the rotors fit the center hub perfectly, they will not fit around the wheel part of the axle. They state in the kit that this 'may' need to be ground down, or you can swap them for correctly-sized ones for $30 plus shipping both ways.

Just wondering what others may have done. I know that a machine shop could grind it out to the correct size. But it is tempting to try a die grinder or dremel at home. Even if not done perfectly, it shouldn't affect the centering at all. Now I remember why I need a lathe.
