Power Slot’s exclusive Vac-U-Slots are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean.  And in wet, raining conditions, the Vac-U-Slot helps push water off the braking surface for better stopping power.

Power Slot slotted brake rotors are finished in a military-spec Type II/Class II Cadmium plating for the ultimate rust resistance.  Although contact with the brake pad will eventually wear out the plating on the braking surface, Power Slot’s Cadmium plating continues to protect the internal cooling vanes that provide critical structural support for the rotor.

For our most performance oriented customers, such as club, and auto-Cross racers, we recommend Power Slot’s Cryo-Treated rotors.

What is cryogenic treatment?  Deep cryogenic treatment is a one-time process that permanently improves the performance and service life of metals from brake torots to gear sets.  Using a proprietary computer-controlled process, the metal is cooled gradually to -300 deg. F and then slowly returned to room temperature and heat-cycled as the final step.
