What all of you are forgetting is the hand brake. It's built into the rear caliper. front calipers will never work.

The FR500C Ford factory built race car uses the OEM equipped rotors and calipers back there...
So that sure answers the question of why would you need to change anything at the back guys.

You all need to spend your money wisely, on things that count...

That is good to know. I am about to rotate my tires again, I will have a peek at the hardware mounting equipment for the calipers and see if they are indeed exactly the same dims. I like the idea of having two piston calipers (a total of four back there).

I will also look at how the e brake works there too.

Not to mention, the ABS system would not be happy
at all and could be quite dangerous in a emergency
stopping situation.
My rear OEM pads are shot and the rotors are worn
as indicated by the 'ridge' on the outside egde but the
front OEM pads dont even look worn at all and the rotors
dont have the 'ridge' yet at the edge.
Seems to me, my rears are taking all the stopping power.

ps I dont have ABS on this stang...
