i've just bought some new alloys for my g, this might sound like a stupid question but : -
a packet of black plactic spigot rings came with the wheels, these clip into the inside of the wheels where it sits on the hub, im summising there for centering the wheels on the hubs ??
the main question is, do they take much weight or do the bolts carry all the weight ?? being plastic i cant imagine them lasting long. can i get a metal set from anywhere ??
