Unfortunately Ford Parts quit supplying the SVT rear brake kit and the so called rally kit (slightly smaller than the SVT rotors). These were the two most common replacement kits. The other common option was to find those from Foci's equipped with advance trac (Anti-lock system) in a junk yard. You can get most of the needed parts "piece meal" but the resulting overall cost would be very high doing it that way.

There are several big brake kits available from major performance suppliers but these tend to be quite pricey and require improving the front brakes to maintain the proper brake bias. A bigger brake on the rear alone can cause it to prematurely lock-up before the front (less weight back there) which is bad for handling and control.
