StopTech® recognizes that great brakes need to look as good as they perform. Performance wheels and tires are best complemented with StopTech®SportStop® Cross-Drilled or Drilled+Slotted rotors.

SportStop® drilled and slotted brake rotors (prefix 127) prevent glazing of the pads, add bite and improve wet and dry braking performance.

Every SportStop® brake rotor is produced from a high quality Centric Parts® blank casting and finished in a durable e-coating for corrosion resistance.

E-Coated Finish

Every SportStop® rotor is finished with black e-coating on both sides of the hat, inside the 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 area can lead to installed lateral run out issues.

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.

Cooling Vane Design

Nearly all SportStop®cross-drilled and drilled + 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.
