: Looking for Rotors that don't rust.

I was wondering if the latest GM rotors made are rust free. I've heard they used a hotter temp prohibiting rust. If not any suggestions?

Take a look at the EBC Black Dash slotted rotors - they're black zinc plated - the braking surface plating wears off during break in and they don't rust. Had 'em for 5 years now - smooth, strong, quiet, rust-free (in Maryland, home of excessive road salting). Redstuff pads.

www.ebcbrakes.com (http://www.ebcbrakes.com) - U.S., automotive - read the links, too. lots of brake info.

www.placeforbrakes.com (http://www.placeforbrakes.com) - discounts and free shipping - worthwhile when you're shipping 60 pounds of gray cast iron.

ANY rotor braking surface will rust - it's polished iron - no way to make it rust resistant. The car sits for 4 days with wet suspension, the rotors get a surface rust skin. That's the grinding noise on the first brake application of the day in wet weather.

The best performing brake rotors are made from cast iron and the braking surface will rust. Nothing else short of carbon fiber has the same heat capacity. You can trade braking performance for cosmetics if you like. The best you can do is cast rotors that are electroplated with corrosion proof coatings everywhere but where the pads rub. Stainless rotors look nice but the heat capacity and braking effectiveness is substandard.

After reading about the carbon fiber rotors on the vette there is no way I would want to deal with them.

FWIW. The Brakes used on a NASCAR Sprint Cup short track car cost $40,000 per wheel and they use cast iron rotors.

Understand they are using Carbon-Ceramic Rotors on some PORCHE.
Brembo has the Monopoly on Carbon-Ceramic-Material (CCM) rotors.
Search and you will find,They are $$$$$.
Sub409 above reflects GOOD rotors for the $$$.
Happy Motoring.

The FNC rotors on the XTS and ATS are supposed to inhibit rust and the pulsing that has plagued my last two cars. I anxiously await word on their effectiveness, but I suppose it's too much to ask for GM to make some for discontinued cars. Where's the Rippy Man?
