SP Drilled and Slotted Rotors are a unique design offering the best combination of cooling and out-gassing. In fact, our design is so unique we would like to go over some of the details. The first thing we will point out on the drilled rotor is the chamfer. Unlike our competition there is no edge on our chamfer. This is accomplished by the use of an outer radius curve rather than a countersink. With the radius curve, or "Sinusoid Curve", it virtually eliminates an edge on the surface of the hole. With no edge, there is less stress build up, thus reducing the chance of surface checking. This smooth surface also makes the rotor more pad friendly by reducing the wear of the pad caused by the friction scraping against a sharp edge.

Advantages of the SP Cross-drilled and Slotted Rotors

• Maximum air circulation for increased cooling
• Increased brake pad bite
• Faster release of brake pad gases
• Improved wet weather braking
• Reduced fade
• Increased Safety and Reliability
• Runs cool…..Looks cool
