SP Performance Slotted Brake Rotors are a unique design offering the best combination of cooling and out-gassing. The first thing we will point out on the Slotted 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.
SP Performance Slotted Zinc Brake Rotors have Electro- plating performed on them 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.
