I'd say the hubs are lathed down standard E series rotors.What you do is remove the wheel studs which knock out the
ABS ring and get the pad surface lathed off and lathed straight down so the 330 rotor can fit over the hub.
I've got a set of 330 brakes for my AU1 and i measured the rotors that are for the AU against the EL GT rotors and the seem to be pretty close to each other. Since both rotors have been used it was difficult to get an exact measurement. Only way would be if you had new rotors.
