When I was doing my research on hubcentric rings for my wheels (which didn't come with any), I found some mixed information. More than a few people state that the hub centric rings only ensure a centered fit and that it's really the force of the lugs against the wheel face (and thus, the wheel against the wheel hub) plus friction that will prevent the wheel from moving.
But I found a BRZ forum that had some custom hubcentric center caps made up for my wheels and ordered a set anyway. I didn't want to have to worry about fitment or movement.
