Do I have captive rotors?
Captive rotors were only on the gen1 Coupe and not all of them had them.
Captive Rotors -
These are the 4 bolt-heads between the wheel studs.

Drilled Recesses -
The PCD of the rotor bolts is 4x100. As you can see here 4 dents have been drilled into the back of the wheels. Without these recesses the wheel will not fit flush to the hub!
