Just purchased new front rotors for an 89. Small thing, rotors(Raybestos)are correct in everyway except for the external casting on the inboard side rubs very slightly on the dust shield(flanged portion).Bearings are also correct(A5 and A12) Yes, I know Ford are much better rotors but I only need these till spring then its being converted to 5 bolt, so I went cheap. Other than better rotor cooling is there any other pros/cons I should be aware of if shields are removed ?? Car is daliy driver. cheers
