you may have some rubbing issues with the 97 brakes since they sit out further then the sn95's. You will also need to swap to newer balljoints or use a .330 spacer. In my opinion it is worth it as I have done this myself and would do it again if I ever buy another stang. I used the sn95 setup though. I would go with the PBR brakes off a 99+ mustang too.
