StopTech slotted brake rotors are designed to withstand high heat conditions from exciting driving, providing enthusiasts with outstanding longevity and temperature control of both the pads and rotors. These slotted rotors are E-coated to prevent glazing of the pads while adding bite and improving wet and dry braking performance.
You can be confident in your brakes while using Stoptech Rotors, due to their state of the art finishing and metallurgy technology. The following procedure is from Stoptech’s archives:
Most StopTech® Sport Rotors are finished with black e-coating on both sides of the hat, inside the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these area can lead to installed lateral run out issues.
Power Alloy Metallurgy
Power Alloy metallurgy is an exclusive feature of many StopTech® rotors. In specific vehicle applications, StopTech works with foundry partners to increase the molybdenum or carbon content of the castings, and to carefully control the cooling rate during production to reach targets for hardness and tensile strength.”
