PowerStop Brake Rotors

Cross Drilled PowerStop Brake Rotors are engineered to keep your brakes 200 degrees cooler. Air flows over and through the drilled holes to effectively dissipate heat and eliminate hot spots. The drilled holes are precision machined in CNC machining centers. If you have ever experienced pulsating brakes and a shaking steering wheel, then drilled rotors are for you.

Warped rotors are caused by excessive heat and the uneven depositing of friction material. PowerStop drilled rotors run cooler than standard or slotted types and prevent warped rotors. Each rotor is treated with a gold zinc dichromate finish to keep that new rotor look.

While slotted rotors do not improve brake cooling, they provide a nice cleaning action to wipe away friction debris. Friction dust and gas gets sandwiched between the pad and the rotor, and this can reduce pad bite. Independent tests show that slotted rotors do not improve the brake performance as much as drilled rotors, but they are structurally stronger to handle severe thermal shock.

PowerStop recommends their slotted rotors for racing, and heavy duty applications like hauling, towing, and fleet use. The silver zinc dichromate finish is highly resistant to corrosion.
