I was under the impression that I would need the hub rings to install the Mazdaspeed wheels. I finally received my wheels today from Showcase, but the install kit that was required did not have the rings in it, only the lugs and socket. I did a search, but this topic was the only one I could find. According to Sabrina, the kit was supposed to include the rings. I'll be calling Showcase in the morning to verify, but I'm pretty anxious to get these on. So does anyone know for sure if I need the hub rings? I did measure the center bore, and it is at 67mm, which tells me that no, I do not need them. But to the other members that have these wheels, msumlim or fichstix, did your install kit include hub rings?
