Fair enough man, I did consider a bolt on caliper bracket though it would have needed to be about 40mm thick in places and I thought that the machining costs would have been somewhat ridiculous. Im sure there are other ways to get aeound this. I however just used what I had lying around so the setup didn't cost me too much , maybe like $200 total for brackets and bearing spacers, the rest was just measuring shit and time. I have some ma61 rear arms complete here and some spare yr22 axles, I could setup some axles and get brackets cut for you but your abit far to just bring my mig over and set your rear end up. You could theoretically just run the rotors and calipers without the backing plate or spacer ring , would still need to weld a bracket to the housing though
