The EBC GD Sport Brake Rotors feature wide aperture slots that help reduce brake temperatures by drawing air beneath the brake pad under load.
GD Sport rotors feature dimples that are resistance to cracking, unlike drilled rotors.
Water mud and debris are expelled from the brake area by the slot pattern which is fully machined to the edge of the rotor for this reason. (Slots that stop short of the rotor edge can cause pocketing of debris and generate a rib on the rotor outer edge.)
