im not they good at wheel things.
Mine has spigot rings all round - if it needs them at front or rear then im sure it wil need them all round - centralises the wheel on the hub - the hub sizes are the same all round.
As for the spacers - I would think they go on the front.
This my not have helped one bit - sure someone knows though
