Would it be possible to make a bracket to fit another car's bbk, like an srt4 for example? It would open many options for bbks and be a lot cheaper than the current options available to us now. I've seen the thread on the bracket for the evo x brembos but I wasn't sure if there was a difference between calipers that would make it possible with a different set.

 

This is possible. It isn't easy, though.
