Heat is the primary cause of ineffective brakes due to fade. There is actually a "boundary layer" of gases that builds up between the pad and rotor surface, which inhibits performance. Here's where Power Slot rotors make a big difference. The exclusive Vac-U-Slots machined into the rotors "wipe" brake pads clean, evacuate gases, and shed heat keeping braking performance intact under high demand. The final touch is a military-spec cadmium plating that gives Power Slot rotors their bright silver finish and protects the rotor from the elements. This eliminates rusty rotor syndrome and enhances the look of custom wheels. Power Slot rotors are manufactured using the highest quality original equipment replacement blanks and all machining is done in house to application specific tolerances to ensure optimum quality control. When used with a combination of a high performance pads, Power Slot rotors will provide superior reliable braking for virtually all automotive applications.
