Power Stop Drilled Rotor - Front Left & Right - AR8317LR

Drilled Rotor, Front Left & Right Pair

Power Stop Cross Drilled Rotors
Power Stops's best selling rotor is engineered to keep your brakes cool. Air flows over and through the drilled holes to effectively dissipate heat and eliminate hot spots. The drilled holes are precision machined in our CNC machining centers. If you have ever experienced pulsating brakes and a shaking streering wheel, then drilled rotors are for you. Warped rotors are caused by excessive heat and the uneven depositon of friction. Power Stop drilled rotors run 200 degrees cooler and prevent warped rotors. Each rotor is treated with a gold zinc dichromate finish to keep that new rotor look. The combinatin of drilles rotors and Power Stop Z series disc pads will provide shorter stopping distance without fade. Power Stop warrants our drilled rotors against cracking for 3 years when purchased with our Z series friction products.

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. Power Stop recommends our slotted rotors for racing, and heavy duty applications like hauling, towing, and fleet use. The silver zinc dichromate finish is highly resistant to corrosion. Upgrade to Nitro-blast cryogenically treated rotors for the ultimate race proven solution to your heavy duty application.
