Don't forget to also let your insurer know about the club reg. Much lower insurance premiums for club reg (or it was when I had an old roadbike on club reg). Something like $50 or thereabouts if my memory is correct! That's a while ago though.
Also I don't think all states recognise club reg. From memory once again I think WA didn't recognise it so couldn't travel into WA. Check these things when going to club reg and planning a trip.
