Every StopTech Sport Rotor is produced from a high quality Centric Parts blank casting and finished in a durable e-coating for corrosion resistance. 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. 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 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. Nearly all StopTech 1-piece rotors have unique slot or hole patterns for the left and right sides of the vehicle.
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.
