Anyone seen this before? I have looked on all the fiche's and can't seem to find it done like this. It looks like someone added this setup for some reason. My 600sx doesn't have these added wheels or shafts. Why would someone do this? What are the advantages? What would I use for replacement bearings/wheels? Could I just cut off those shafts if I had to? Ugh.. I feel like a n00b trying to figure this out lol
