My Rotorpros have rust accumulating in the slots, and they look like crap. Will this happen with the BBKs or maybe a more expensive replacement rotor?

 

Do they look like this?? Sorry for the sucky picture but it's from my cell phone. So I would say yes it's normal. Mine were zinc plated and looked good for a year or so but you have to remember nothing touches the slot or holes to clean them. You can pull the wheel and give them a light spray painting with some flat black and clean the brake surface to make them look better. But I believe any brand will look the same in a couple of years.

 

Bah, that's exactly what I mean. My car sits for eternity so I'm sure I'm making it even worse.

So even the rotors that come with a big brake kit aren't coated in the slots/dimples? Rats!

 

Accually I believe the slots and dimples are zinc plated also. But over time the coating does rust also.
