SP Performance Cross Drilled and Slotted Brake RotorsSP Performance Cross-Drilled and Slotted Brake 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 edgeSP Performance Drilled and Slotted Brake Rotors With Optional Bright Silver Plating:Electro- plating is performed on our rotors to provide a brighter finish which is more appealing to the look of the rotor. When plating a rotor a metallurgical bond is formed between the plating and steel forming an iron rich alloy with tenacious bond where it will form its own protective oxide layer. Electro- plating is very effective in combating the corrosion of the rotor.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??????¼..Looks cool
