Extreme Performance 1998-2002 F-Body and Firebird - Drilled-Slotted Rear Rotors - One Pair Extreme Performance cross-drilled and slotted brake rotors are manufactured on CNC machines using CAD-CAM design for perfect balance and alignment. These rotors provide you with maximum stopping power, reduced warping, and longer life. The cross-drilled holes and slots provide an exit route for gasses and dust, resulting in better heat dissipation and less brake fade under hard use. Other solid-surface rotors allow gasses to create a cushion between the pad and the brake rotor, resulting in poor brake performance. The cross-drilled holes and slots clear away harmful gasses, restoring full pad-to-rotor contact. These rotors are a terrific performance upgrade when replacing your OE rotors.
