StopTech Sport Rotors are also available with an optional cryogenic treatment. Although cryogenic treatment is invisible to the naked eye; many fleet customers are sold on its ability to extend the service life of the brake rotor. Deep cryogenic treatment is a one-time process that permanently improves the performance and wear characteristics of metal components; from brake rotors and engine parts to machine tools and gear sets. All new StopTech Sport Rotors may be ordered with cryogenic treatment for an additional fee.
StopTech® 128 High-Carbon Cross-Drilled Rotor
StopTech® recognizes that great brakes need to look as good as they perform
Performance wheels and tires are best complemented with StopTech® 128 Hi-Carbon Cross-Drilled Rotor.
StopTech® slotted, drilled and drilled+slotted brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance.
Every StopTech® Rotor is produced from a high quality Centric Parts® blank casting and finished in a durable e-coating for corrosion resistance.
Engineered to look good behind the wheel and perform at the same time
StopTech® 127 Hi-Carbon Cross-Drilled & Slotted 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® 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.
