These rotors are way under-rated. I used to be a car flipper. And I used to use Autoshack Rotors and then pair them up with Evolution Ceramic Brake Pads w/ Hardware. Drives like a new vehicle everytime with any brake job I did. Never had issues with any of their stuff. However the Autoshack Brake Pads are a little iffy and cheap/poor quality. Awesome Video & Great looking GMC btw!
