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. Centric PremiumTM rotors provide a painted hat and edge for corrosion resistance. The paint used is a robust resin-modified material that is chemically resilient withstanding 120 hours in salt chamber testing..
