PowerStop Evolution Drilled and Slotted Rotors – One Pair – fits 1977 – 1996 Impala SS, Caprice, and other models with our 12.8″ front rotor big brake kit.
We CNC mill these rotors in-house with a 5 on 5″ bolt pattern and enlarged center bore.
Power Stop’s Evolution drilled and slotted rotors provide cooler brake temperatures as a result of dissipating the gasses burning off of the brake pads. This “de-gassing” or “out-gassing” will keep the pads in contact with the rotor, resulting in less brake fade after repeated stops. Improved bite on the brake pads will also enhance braking performance from each option. All Power Stop rotors will promote improved wet-weather braking, as water is swept between the pad and rotors. Each of these rotors is analyzed for its specific application, vane structure, and construction to determine the optimum cross-drill or slot pattern. Patterns are designed on a CAD system to ensure that strict design criteria are met, and they’re run on CNC machines for absolute accuracy. These rotors are engineered with a directional pattern, and each hole or slot is counter-sunk with Power Stop’s own designed tooling. For replacement or rotor upgrades, order the Evolution model recommended for your vehicle.
