Drilled and slotted rotors provide the looks and functionality of both cross-drilled rotors and slotted rotors combined. Drilled and slotted rotors are not recommended for track use due to the abuse they will take. The drilled holes in the rotors will be prone to stress-cracking, The combination of the drilled and slotted pattern does work great with heavier vehicles, especially vehicles that will be towing heavy loads. Since heavier vehicles create more heat in the braking system, the drilled and slotted rotors will help provide the best stopping power by keeping the rotors and pads the coolest. By keeping the braking system cool with the drilled holes, and by pushing the gasses and brake pad dust away from the rotor with the slots, this will provide the best bite to stop any vehicle.
