Need help identify some parts

[Tinted911SC]

I have recently been working on cleaning the garage and have some things people might be interested in.

I have a set of what I believe are Porsche 944s front Calipers.

I'm not so sure about the rotors, they dont look factory and look like they might be missing something.

If you could help me identify these I would appriciate it.
