Power Slot slotted rotors utilize a Vac-U-Slot design to shed heat and gases. Ridding the rotor of heat and gases greatly improves stopping power. And in wet, raining conditions, the Vac-U-Slot helps push water off the braking surface for better stopping power.  The Vac-U-Slot also serves as a visual wear indicator. The slot is machined to the rotor’s minimum thickness where it crosses the outside edge. If you cannot see the slot along the outside edge, the rotor has worn down to its discard depth.

Power Slot rotors are constructed using OE replacement blanks, meeting and often exceeding OE specifications. They are then machined in house by Power Slot and finally cadmium plated to protect the rotors from corrosion and give them a nice silver finish. Power Slot rotors will perform better than OE replacement rotors and have a longer life span under normal braking conditions.

NOTE: Power Slot rotors are OEM size and designed to work with your stock calipers. No modifications necessary.
