Cooling Vane Design
Nearly all SportStop Drilled and Drilled and Slotted rotors have unique drilled 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.
Power Alloy Metallurgy
Power Alloy metallurgy is exclusive feature of Power Slot and SportStop 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.
