Another point of advise I forgot to mention!Use a wire cup brush,or sanding pad on a angle die grinder to remove the rust inhibiter on the face of the rotors before installing.Remeber to wear safety glasses!!!!!Also,use 3 lugnuts equally spaced,or somewhat spaced,and hand tighten with ratchet going to each of the 3 studs,until they are snugged,and then install the other two lugnuts.I think I torqued mine to 135 ft.lbs.,using a 1/2" drive torque wrench...
