Disc Rotor dimensions

What are the critical dimensions/requirements for a front disc rotor swap? Apart from the PCD and total diameter. I hear that the thickness of the rotor is critical as well. Is this true?

Yes, the thickness is important because you don't want to resurface the rotor past this limit. I don't have the numbers off hand, but can find out when I get home later tonight.

And this would be the standard for which car? Do you have the standard for a 98 ITR?
