The Absolute brake rotor design is dimpled and slotted.  Dimples are bored holes that are drilled just beneath the surface of the brake disc.  Dimples on a brake rotor are meant to act similarly to slots by creating friction between the brake rotors and pads as well as clearing out debris and hot air, which helps to boost stopping performance.  Furthermore, dimpled brake rotors achieve the same look as cross-drilled brake rotors at the same time preserve the structural integrity of the rotor. This particular design is recommended for the more aggressive driver that desires an assertive, sporty look.
