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.
