    Is Zinc coating rotors a waste on a track car?

    Guest-only advertisement. Register or Log In now!
    So I'm thinking that when I got a zinc coating on rotors I used out on the track it was a waste of money and I wouldn't do it again. My reasoning is that zinc has a pretty low melting point of 787 F and hard braking will easily generate temperatures that exceed this. After one track season the zinc coating on the non-swept portion of the discs is long gone, replaced by iron oxide.

    Any contrary thoughts on this?

    i am not surprised by your findings & agree with your theory..... zinc is not the most durable of coatings.....

    Coatings are applied to rotors to prevent corrosion. If you have dedicated track parts then there really is no need.
