Need new brake discs?

Hey, so I painted calipers today, just one side, I paused with next ones because I am thinking of getting new brake discs.

They look pretty bad I am sure you can see, very rusty and I don't like what it looks like.
As you can see, even with painted caliper, it looks horrible.

I am not sure what the part number is or where to get them online...
On realoem website I checked, and it has two part numbers not sure which one, I mean two part numbers for front and for rear, 4 numbers in total. help?

Car is: E46 318i 1.9L

You can always scrape the rusty portions with a wire brush and use the same caliper paint on the rotors themselves. Just don't get it on the friction surface, or the mating surface where the wheel bolts on. New ones are going to do the same thing in short order.

Wow, 318 brakes are tiny!

Oh, so it's alright to paint disc/rotors areas where there is no friction? it's a high heat paint btw up to 800 C

Yes, not where the pad hits and not where the wheel hits. Obviously the paint will stick better on a new rotor, but in my experience caliper paint sticks to rusted surfaces pretty well.

I'm pretty sure the OP is talking about the sweep area of the pad on the rotor and not the hub. You have some rust on the outer perimeter and there is also a bit close to the hub. There is something going on where you aren't getting even clamping. My whole rotor disc is bright and shiny.

Look at the size of the pad...these 318s have a much smaller swept area than the US cars. Those rotors are perfectly fine, just ugly because of the rust (which is typical on all BMWs afaik).

So it should be okay painting them? I mean it brakes fine and on time, but looks very very horrible.

There should be no rust on the swept area of the rotor. Rotors and pads are sized so they work in tandem to hit the entire area of the rotor. I'm pretty sure his caliper guide bushings are out of whack.
