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 2011 - 2018 Audi A7 Quattro, 2012 - 2016 Audi S4, 2012 - 2017 Audi S5, 2012 - 2018 Audi A6 Quattro, 2013 - 2018 Audi Q5, 2014 - 2018 Audi A6, 2015 - 2016 Porsche Macan, 2016 - 2017 Audi A5, 2018 - 2018 Audi A7
