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 Premium e-coated rotor with advanced metallurgy that greatly reduces pad squeal; Especially effective with higher friction; European style brake pad compounds; Added Molybdenum and Chromium to resist rotor cracking 2010 - 2017 BMW 535i GT, 2011 - 2013 BMW 535i, 2011 - 2015 BMW 740i, 2011 - 2015 BMW 740Li, 2011 - 2017 BMW 535i GT xDrive, 2011 - 2017 BMW 550i, 2011 - 2017 BMW 550i xDrive, 2012 - 2017 BMW 640i, 2012 - 2017 BMW 650i, 2012 - 2017 BMW 650i xDrive, 2013 - 2015 BMW 740Li xDrive, 2013 - 2015 BMW ActiveHybrid 7, 2013 - 2017 BMW 640i Gran Coupe, 2013 - 2017 BMW 650i Gran Coupe, 2013 - 2017 BMW 650i xDrive Gran Coupe, 2014 - 2017 BMW 640i xDrive, 2014 - 2017 BMW 640i xDrive Gran Coupe, 2015 - 2015 BMW 740Ld xDrive, 2015 - 2015 BMW Alpina B6 xDrive Gran Coupe
