Brand-new pair of 2 directional (one left hand & one right hand) high performance drilled and slotted brake rotors for 1982-1988 Buick Regal, Grand National, and 1987 GNX.
Data shows the holes in the rotors can lower temperatures by 180 degrees F (82 degrees C). Lower temperatures can mean less wear on the brake pads, less build up of friction material deposits and shorter stopping distances. Slots help keep dust and gases from accumulating on the rotor surface, giving the brake pads more bite. Both holes and slots can help get water off the rotor surface.
These brake rotors feature pre-installed new inner and outer races as well as ready to install pre-roughed surfaces.
