This is a set of factory Porsche Front steel rotors. Each time you change a rotor on center locking wheels, Porsche recommends replacing the rotor assembly hardware (see related item below).
NOTE: These sets are not compatible with the Ceramic Braking System or vehicles with 5 lug bolts. This set is intended for vehicles with one center locking lug bolt (2010-2012 Turbo or Turbo S models).
