Is there a performance disadvantage to non rusting rotors?

[Space Ghost]

I'm really tired of my wheels getting dirty from the rust that forms on the rotors. It really sticks to my flat black TE-37's. A lot of the aftermarket company's have non-rusting rotors but I dont want to sacrifice braking performance. Does anyone have any expierence with these? I only track the car 2-3 times a year and have been using upgraded pads and fluid with great success. Thanks for your input.

It depends on the brand, typically a rust free rotor has a gloss black coat on the hub to prevent rust. This is only for aesthetics and would not effect performance- all else being equal about the rotor.

Thanks for the response. They advertise them as anti corrosion zinc coated and the rotor is usually gold in color.

Which will be gone in 100miles or less.

That protective coating will disappear pretty quick, and they'll rust just like any other rotors.

Will high temp engine paint stand up to the heat at the hub?

are you sure the dirt is from the rust of the rotors? not the pads?

oem pads are extremely dusty.

I'm sure it is a combination of both. It just seems to really grip onto the flat black paint and I do clean them regullary. I'll have to start painting them with each detail.
