Description of Power AR82121XPR Evolution Drilled Slotted
Drill holes keep brake rotors up to 180 degrees cooler. Slots keep a clear contact patch between the pad and the rotor. Increased braking performance. Look great behind custom (or factory) wheels.
Great rotors built in when it's time to hit the brakes. The only complaint is when the new ones stop like now! When the brake is applied after a short break, perfectly installed in 2017, still satisfied.
Pros
Drilled holes keep brake discs cool up to 180 degrees
