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 & Slotted rotors. SportStop Drilled & Slotted brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance. Every SportStop Drilled & Slotted brake rotor is produced from a high quality Centric Parts blank casting and finished in a durable e-coating for corrosion resistance. SportStop 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 SportStop cross-Drilled & Slotted rear replacement rotors is a great way to match the aesthetics of a StopTech Big Brake Kit with the cross-Drilled & Slotted rotor option. *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 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 & Slotted rotors have unique Drilled & Slotted 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 & Slotted hole never touches a cooling vane.
StopTech is the high performance and racing brand from Centric Parts - a leading innovator of world class brake components and systems for production-based race cars and high performance vehicles on the street and track. StopTech was the first to offer balanced brake upgrades for production cars and remains the worldwide leader with over 700 platform offerings that dramatically improve overall braking performance.
StopTech was founded in 1999 with the singular mission of becoming the leading aftermarket manufacturer and supplier of high performance brake components and systems. The company founders sought to challenge the status quo in known brake technology, and set new paradigms for brake system upgrades. United by their passion for racing and high performance vehicles, the company quickly earned a reputation for quality and performance both on and off the track.
StopTech’s industry-leading technologies and materials - from rock solid calipers to ingeniously efficient heat handling rotors - have earned the company four patents and numerous industry honors over the years. In 2013, StopTech earned full ISO/TS 16949:2009 Quality Management System certification for the design and manufacture of automotive brake systems and components, allowing the company to supply OEM vehicle assembly plants directly in a Tier 1 relationship.
StopTech has been awarded the highly coveted TÜV approval on several big brake kits. StopTech kits successfully passed TÜV’s demanding series of tests that range from performance and durability, to proper fitment and ease of installation. Although TÜV certification is not required in all countries, TÜV approval demonstrates that StopTech’s Balanced Brake Upgrades meet the rigorous standards set by this respected German agency. StopTech Big Brake Kits have been awarded a Teilgutachten. The complete kit is certified to run on a particular application, so customers do not need to pay for further testing with the TÜV agency.
