PowerSlot Performance Brake Rotors

Power Slots

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. These 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.

E-Coated Finish

Every Power Slot rotor is finished with a 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 areas can lead to installed lateral runout issues.

Double Disc Ground

Power Slot rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

Machined Finishes

Power Slot rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

Mill Balancing

Power Slot brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

Split Castings

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

Directional Vane Design

Most Power Slot rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Power Slot has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

Power Alloy

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).

904/28/2013M3Product has performed very well. Really impressed the design and engineering of product. Great product for the price
104/10/2013Mustanghad some bad vibrations at braking plus had to switch the left and right as what was indicated was wrong.. which reduced some of the vibrations!
