Would any of these parts be interchangeable with what I posted in the first post?
These brackets are cheaper, for example.

These discs are more along the lines of what I'm looking for as they're drilled and slotted.

And then there are these calipers, but they're $150 each. What care are these from? If I could pick up a set somewhere else for less money, that'd be good. I'm trying to get some good brakes, but without spending $800. I'm not pushing ridiculous power or anything, I just want to be able to stop on a dime and have good brakes for autocross days.

Edit: It seems that the calipers are 2006 Mustang GT calipers. Could somebody confirm this?
