GenVibe - Community for Pontiac Vibe Enthusiasts

I just got my new wheels in today (pictures to come) and I need to know how big the Vibe hub is so I can get the hub-centric rings. The wheels are Motegi so I know they come with a 73mm hub opening that has to be sized down to...?

the matrix hub register measures 54.1mm. i would think vibe's are the same. most aftermarket rims measure 73.1mm at the hub.
