Brembo Rotors - Sport Series Slotted (Rear)

Some rotors have cooling fins between both faces are called "vented" rotors, or drilled which are called "cross-drilled" rotors. Replacing your factory rotors with aftermarket rotors will improve your braking power, which can be a high priority if you add performance parts to your truck. You don't want to beef up the performance of your truck without also improving your stopping power.
