CROSS-DRILLED The addition of high performance street pads provide you with higher resistance to fade, higher maximum operating temperature, and better initial bite to allow consistent deep braking into corners. Superior resistance to cracking due to thermal stress Increased molybdenum content that extends reliability, service life and helps reduce NVH "noise" issues Cross drilled brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance.
