Do all 2000s have HP2 (4 pad, from my understanding) calipers? Or is it possible for my car to have 2 pad calipers?

My rotors seem to have the 22mm offset. Is there any ryme or reason to which cars got which offset of rotor?

I have a 2000 2.7t Quattro 6 speed.

 

Not all 2000's , just the 2.7T and 4.2 motors. 2 pistons, 4 pads per wheel.
