Your original post indicated your car was SPF1639. The Superformance documentation extract in Post #9 of this thread provides you with a component listing of the calipers and rotors used in SPF cars 700 through 2636. Your car fits in this range of Superformance vehicle numbers. That means the braking system, as delivered by Superformance, uses the braking system components identified in that extract. The extract identifies your car as having been built with Wilwood calipers and one-piece OEM discs from GM on the front and Ford on the rear.
Someone could have modified your brakes between your car's date of manufacture and when you bought it. If they did, then the Superformance documentation will no longer reflect the braking system on your car. If they did not, the documentation extract in post #9 accurately reflects the braking system your car came equipped with and uses today.
If your brakes have not been modified from the original Superformance provided units, the only components you will be able to find at your local parts store will be the rotors. The pads and anything caliper-related will necessarily have to be sourced from Wilwood.
Whether or not you use drilled and or slotted rotors is entirely an owner-determined election. They are available. If you don't want them, don't buy them. If you do want them, buy them. That is entirely your call. Whether or not your rotors are "standard Ford T-Bird rotors" or not has no bearing whatsoever on whether or not your calipers will need servicing. The only determining factors with respect to servicing the calipers will be their condition, the condition of the brake pads, and what you intend to do about it — this is not rocket science.
