I believe you are referring to the Bullitt calipers. They are 13" brembos, painted red.
There are three flavors of the exact same caliper:
1) Bullitt, as described above
2) Cobra, which has black calipers with "Cobra" in silver
3) Anniversary Cobra, which has red calipers with "Cobra" in white
All of the above are the same exact caliper (except for the paint job) and came from Ford with the same exact rotor (13" vented solid Brembo). The typical price for the entire upgrade is about $400 or so (there are often some good deals on eBay, too). This is a significant upgrade for the price. The basic gotchas I have seen in doing the Cobra upgrade are:
a) You need at least 17" rims (and I am not sure all 17's will work, but I know Bullitt rims are fine).
b) The doughnut spare tire will no longer fit.
c) The GT hoses have a different fitting into the caliper than the Cobra calipers, requiring Cobra hoses instead of re-using stock GT hoses.
d) I have heard that upgrading the OEM solid Brembo rotor to slotted and/or cross-drilled can result in excessive pad wear and is not required unless car will see serious auto-x time (although it does look cool).
