StopTech Sport Rotors are premium quality replacement brake rotors that 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

Power Alloy metallurgy is an exclusive feature of many StopTech^® rotors. In specific vehicle applications, StopTech works with foundry partners to increase the molybdenum or carbon content of the castings and to carefully control the cooling rate during production to reach targets for hardness and tensile strength.

Cooling Vane Design

Nearly all StopTech^® 1-piece rotors have unique slot or hole patterns for the left and right sides of the vehicle. For these directional patterns, straight vane or pillar vane rotors are used to ensure that a drilled hole never touches a cooling vane.

Machined Finishes

StopTech Sport Rotors feature 100% fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component. In addition, StopTech Sport Rotors are inspected for balance and mill-corrected to a tolerance of less than 2oz. per inc

Directional Vane Designs

Most StopTech Sport Rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Centric has improved the design by using directional vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight or pillar vane design. The directional vane is a more efficient air pump providing increased resistance to brake fade and faster thermal recovery to temperature spikes generated by aggressive or repeat stops.
