Not sure what it's called but it's part of the disc that doesn't have pad contact.

Mine are getting a bit rusty and unsightly so was wondering if I can spray them silver/grey without affecting the disc/pad operation?

It's called the disc 'bell' (at least that's what I've always called it smile).

It probably wouldn't do much harm painting it, but you'd need to use VHT paint, cos discs get fking hot, and I guess there's a slim chance that it would encourage distortion of the disc and/or cracking around the drilled holes, on account of the paint will create a slight insulation effect that makes the discs run that little bit hotter.

Paint away. Lots of manufacturers paint them now. Honda started painting them ~8 years ago because of the number of people complaining about rusty brake discs. In fact, if memory serves in one year it became Honda's biggest warrenty claim!

You could consider getting them zinc plated.

Agreed, the only issue I foresee is it looking unsightly if the paint starts to come away after the wheels have been on and off a few times.

No issues with performance of the disc etc at all.

Yes contact point wears out, but I'd rather my brakes work than look good.

So you end up with a good looking disc that also works.

Crikey! So do they get a polished/reflective face where the pad and disc contact? Or does the whole disc stay looking like that?
