Brake rotors aren't exactly known to be the cleanest part of the car. In fact, the brake rotors often become these ugly little gremlins that you are forced to accept as part of your car. But the truth is not all brake rotors have to be hideous. There is a reason brake rotors develop rust and start looking like ancient archeological dig items after a few months, but that's not something we have to live with in today's age.
up on brake rotors is not only unsightly, but it's detrimental to the brake rotors structural integrity as well as performance. Excess rust starts to eat away at
the brake rotor, creating a brake rotor that has varying thicknesses and is
exposed to heat cycles. This doesn't sound like a big deal, but let's take a
closer look at it. When metal heats up, it expands.
Conversely, metal also shrinks when it cools down. Now picture a brake rotor that is heating up and cooling down, with varying thickness. That means each part of the rotor is expanding and shrinking at a different pace than its adjacent counterpart. This occurs at every heat cycle and can lead to premature wear, cracks and balancing issues.
We make sure to coat our brake rotors in a zinc coating in house. Because we control the zinc process ourselves, we offer the choice of two finishes on the zinc treatment on any performance BrakePerformance Rotor: Bright Silver and Stealth Black. Although the treatment isn't a guarantee against rust, it surely does help than using an untreated rotor. Best of all, you reduce the unsightly rust that forms!
