StopTech Slotted 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 slotting 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. Slotted 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 2012 - 2015 BMW 328i, 2012 - 2015 BMW 335i, 2013 - 2013 BMW 328i xDrive, 2013 - 2015 BMW 335i xDrive, 2013 - 2015 BMW ActiveHybrid 3, 2014 - 2015 BMW 328d xDrive, 2014 - 2015 BMW 328i GT xDrive, 2014 - 2015 BMW 335i GT xDrive, 2014 - 2015 BMW 428i, 2014 - 2015 BMW 428i xDrive, 2014 - 2015 BMW 435i, 2014 - 2015 BMW 435i xDrive, 2014 - 2015 BMW M235i, 2014 - 2016 BMW 228i, 2015 - 2015 BMW 435i Gran Coupe, 2015 - 2015 BMW 435i xDrive Gran Coupe, 2015 - 2015 BMW M235i xDrive
