They were new 2 months ago, why are they rusty already!?

Perfectly normal, especially just after rain. Check a few other cars.

as above.....

have a look at any car's discs during/after rainfall. it's just surface rust, ie the acid rain causing a slight surface corrosion,it's perfectly normal.

it's the actual lip of the disc you ought to concern yourself with and where the pads make contact.

spotting or slight surface rust will go when dry or used.

you'll notice it even more when you've washed it, your entire discs will turn rusty bronze.

As the discs are not treaed the rust forms a thin surface layer... nothing to worry about..
