hub centering rings

[MountaineerSTi]

Someone tell me how necessary hub centering rings are for aftermarket wheels (used only for autocross). I have the correct conical lugnuts for the wheels and installed them and it seems fine to me.

Are there local shops that sell them if I need to have them? The outside diameter would be 73.1 and the inside diameter would be 54.1

Thanks

for autocross only centering rings are not a must... use them if you have them.. otherwise tighten your lug nuts to the proper torque in a star pattern and you are good to go!!
