I need the truth about wheel adaptors

First I would like to thank everyone that responded to my question. I think the best way to go is to change to the BBP and forget about adapters for safety sake. I put allot of time and money into the build and after all the info all of you gave me I think that would be the best way to go. Not sure what all I have to change, I think the axels, rear drums & front hubs & rotors, maybe more. If anyone has the parts I need i would like to hear from you. I will start a new thread in the proper place to see what responce I get. Thanks again to all
