Hello Ravio,
that way to do it, like offroadtarvike or offivaruste is most common and simple + cheap way to get fe. toyota discs suite for C30X axles
those two extra pieces are "hightech" in my eyes, but it doesnt mean that they are bad or useless
I think there is no need to weld any extras, main point is get those surfaces straight against discs, and if you make holes and "worms" for 6 x 139,7 circle, you have many variations for rims
there is some picture from my project, i used toyo discs, wilwood and rover brakecalibers
