seems like all he would have to do is create a bracket to fit over whatever disc he wanted to use, The actual caliper could be ordered separately.... no?
Yeah I guess you can just do that. I dont know if all the brembos bolt up the same way, but if they do you will just need to buy the bracket for them and you'll have to make sure they will fit you wheels. You can probably fit used on ebay from cars that come with them, like porsche and such to make it cheaper for you.
