dad already has the big 4 pots on his, so no point in upgrading

i can however steal his spare hubs if this idea pans out, and try it with his rotors (may as well go for the bigger ones, haha).
which bolt on affair are you refering to? ls400 setup onto a jza80 or jza70?regretably the caliper setup on an a70 is quite a bit different

hence wondering if can swap the entire hub.
hunt also mentioned that the abs sensors may not work, so i'd loose my abs, which is something i'd rather not mess with too much, so may have to forget this idea and go back to adapters to suit.
