They maximize air circulation, and with absolutely no sharp edge, our 'chamfer' reduces the possibility of heat checking and increases both rotor and pad life.
All SP Performance Rotors are manufactured to OEM specifications, machine balanced and gray ZRC Coating. By keeping the surface temperature down, this nearly eliminates heat checking and warping. By eliminating the sharp edges on our Cross Drilled holes, it greatly reduces the chance of cracking by moving the air and brake dust from the disc brake surface while reducing the surface temperature.
SP Performance Cross Drilled and Slotted Rotors are at the top of the list for performance rotors. SP Performance Rotors use only the finest materials from very select factories. SP Performance drilled and slotted rotors gives the advantages of both drilled holes for cooling and slots to expel gasses and brake dust.
