Turbo Groove automotive brake discs have a widened, arcuate gap that increases the flow of cool air, lowering the temperature of the brake pads and brake disc, while draining dust, dirt and hot gases better than a straight line, which can rust and become ineffective. Drilled holes remove surface gases when braking from high speed, while not weakening the structure of the disc as in through drilling.
