Why so rusty inside and what's with the pitting ?

The car is only 6 years old.
I don't think it affects functionality but it seems strange.

What sort of tool do I need to remove that nut ?

I assume it's to remove the rotor ?

Rust is normal.

Not strange at all, its your axle nut.

~36mm socket. Don't remove it!!! (Unless you need to pull axle)

It does not secure the rotor. There is a hex set screw for that.

Ahhh, OK. I'll leave that alone
