Kinda tired of the crusty/rusty rotors on my GS4.
I see where newer cars have that gray coating on the rotors that prevent them from rusting.
Is this an option for 2nd Gen GS's? If so, know where they can be obtained?

Thanks in advance.

 

Plenty of options out there, you just need to look for those that are zinc treated.

Centric premiums are a good option. Rock Auto has them. Do not go with the Centric C-tek series economy rotors if you want to avoid rust, though they are attractively priced they are not treated.

Note, the rotor face on any rotor, will always rust if the car is not being used. If price is a factor, you can use a high heat spray paint on the rotor hat portion to prevent rust on the a non-treated rotor.

 

I have centrics and brembo blanks on all our cars with no rust

 

As fastnoypi mentioned, Centric does offer premium rotors with a rust preventative coating around the hub and/or venting areas. The brake surface will be exposed no matter what rust preventative treatment is applied. These preventative measures can be added to standard rotors such as the CTek rotors as well and will probably save you some money in comparison to the Centric Premiums. Hope that helps.
