Centric 125 Series High Carbon Alloy Brake Rotors contain an advanced metallurgy that greatly reduces the possibility of pad squeal especially with higher friction, European style brake pad compounds. Proprietary Molybdenum and Chromium alloys resist rotor cracking during high performance use or repeat stop situations. This alloy also increases the friction couple improving brake performance and stopping power. Increased Chromium and Carbon content is also more resistant to oxidation. Centric Premium 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 2013 - 2016 BMW 328i xDrive, 2013 - 2017 BMW 320i xDrive, 2014 - 2015 BMW 320i, 2014 - 2016 BMW 328d, 2014 - 2016 BMW 328i, 2014 - 2016 BMW 328i GT xDrive, 2014 - 2016 BMW 428i xDrive, 2014 - 2017 BMW 328d xDrive, 2016 - 2016 BMW 428i, 2016 - 2016 BMW 428i Gran Coupe, 2016 - 2017 BMW 330e, 2016 - 2017 BMW 330i, 2017 - 2017 BMW 330i GT xDrive, 2017 - 2017 BMW 330i xDrive, 2017 - 2017 BMW 430i, 2017 - 2017 BMW 430i Gran Coupe, 2017 - 2017 BMW 430i xDrive, 2017 - 2017 BMW 430i xDrive Gran Coupe
