Cross Drilled Vented 1-Piece Front Brake Rotors (C34142C-P) by SP Performance®. Quantity: 2 Per Pack. Don’t get the fades! Aggressive driving, stop and go traffic, and emergency stops can give you the fades. Brake fade that is. SP Performance Cross Drilled Rotors stop the fades by venting gasses through the holes bringing your vehicle to a screeching halt. SP Performance Cross Drilled Brake Rotors have a design that offers the best possible cooling and venting of brake pad gasses, brake dust and moisture. Unlike SP Performance competition there is no sharp edge on SP Performance 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.
