Power Slot Rotors

Power Slot – Faster Stops Made Easier

Power Slot reinforces their motto – Premium Quality Equals Premium Performance – by emphasizing four basic principles:

Research & Design

Every Power Slot brake rotor starts off as a premium quality blank casting sourced from the best foundries in North America, Europe and Japan. They make sure their products meet and exceed the features of the O.E. (original equipment) rotor, paying special attention to:

Casting grade and metallurgy per SAE J431 Brinnel hardness (BHN) and surface finish (RA) Critical design elements such as the number of cooling vanes, vane direction, heat dams and plate thickness

Premium Sourcing vs. Economy Sourcing

Some competitors will sacrifice quality by using inexpensive offshore castings made in China or other emerging countries-of-origin. While these economy rotors might be okay for light-duty city driving, they won’t hold up under the rigors of high-performance, fleet or severe duty driving. Typically these economy rotors are made of inconsistent, porous material and have less cooling fins that their O.E. counterpart. These fins also serve to reinforce the rotor and guard against warping.

These three rotors are all intended for the same vehicle. Only Power Slot matches the OEM dimensions. The two other offshore competitors use fewer cooling vanes and thinner plates.

Structural Integrity

A drilled rotor may look good, but it’s not the best choice for performance or severe-duty use. When you drill and O.E. sized rotor, you weaken it and cause stress points that can lead to cracking and possible failure.

Also, drilled rotors lose considerable surface area and mass compared to slotted rotors. That means less active braking area for the brake pad to make contact on the rotor. For the best combination of performance and durability, stick with Power Slot slotted rotors.

Power Slot rotors maintain 96% of their active braking area while cross-drilled rotors retain only 85-93% and drilled & slotted rotors retain only 80-90%.

Military Spec Plating

Power Slot applies a proprietary military-spec Cadmium plating on every single rotor they sell. This protects the rotor from harmful corrosion throughout its life. More importantly, careful preparation of their rotors prior to plating ensures that the Cadmium will evenly adhere to the unmachined surfaces inside the cooling vanes. Other competitors use inferior Zinc plating on their rotors, or no plating at all! In salt spray testing, Power Slot’s Cadmium plating lasted up to 60% longer than Zinc.
