StopTech® Slotted, Drilled and Drilled+Slotted Sport Rotors
StopTech® recognizes that great brakes need to look as good as they perform. Performance wheels and tires are best complemented with StopTech® Slotted (prefix 126), Cross-Drilled (prefix 128) or Drilled+Slotted (prefix 127) Sport Rotors.
StopTech® slotted, drilled and drilled+slotted brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance.
Engineered to look good behind the wheel and perform at the same time
StopTech® Sport Rotors look great behind custom wheels, improve the initial bite of the brake pads, and help wipe away the debris that forms between the pad and the disc. A set of StopTech® rear replacement Sport Rotors is a great way to match the aesthetics of a StopTech® Big Brake Kit.
Most StopTech® Sport Rotors are finished with 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 area can lead to installed lateral run out issues.
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.
