Not all Iroc Z's have rear disc brakes. It was an option for all Camaros not just the Irocs for the rear disc brakes. Most likely if your car has the code G80(RPO codes are listed in the glove box in the center console) then it will have Rear disc brakes.
However ALL 5.7L IROCs do have rear disc brakes.

No, the 2003 Camry does not have disc brakes on the rear of the vehicle.
On a Ford Explorer : There are disc brakes on the front and ( starting with the 1995 model year ) there are disc brakes on the rear also ( instead of drum brakes on the rear )
it either has front disc brakes and rear drum or it has front and rear disc bakes. look for a flat disc in the front and back - those are front and rear disc brakes-they take pads. The drum brakes take shoes.

You could get a 5.7 liter (350) but it had to be in the IROC Z package , If memory serves me right it also had to be automatic and with four way disc brakes. Most all you find out there are 5.0 liter (305) and have drum brakes on the rear. My father ordered an 87 IROC in the fall of 86 with a 5.7 Liter.
If yours has the rear disc then they all have them.
