StopTech Drilled Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling aids with heat and brake dust dispersal, prevents glazing of the pads, adds bite and improves wet and dry braking performance. Built to last, the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation, better crack resistance and increased performance. Premium e-coated rotor with advanced metallurgy that greatly reduces pad squeal. Especially effective with higher friction, European style brake pad compounds. Drilled for increased bite, improved looks and better performance 2011 - 2016 BMW 535i xDrive, 2011 - 2017 BMW 528i, 2011 - 2017 BMW 535i, 2012 - 2016 BMW 528i xDrive, 2012 - 2016 BMW ActiveHybrid 5, 2014 - 2017 BMW 535d, 2014 - 2017 BMW 535d xDrive
