Power Slot® Rotors
Power Slot® rotors are 1-piece, slotted, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer.
Launched in 1998, Power Slot® was the first premium slotted replacement rotor program in North America. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Power Slot® covers more than 2500 applications, all machined in Power Slot's®California manufacturing center. Every Power Slot® rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.
Power Slot® rotors feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction, or “bite,” amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions
Power Alloy metallurgy is another unique feature in many of Power Slot's® rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Power Slot's® continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Power Slot's® top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).
