ADVANTAGES
The wider slot actually draws cool air across the pad surface keeping pads and rotors cooler.
They also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale and become ineffective.
The blind drilled holes break down surface gases when braking from speed but do not weaken the rotor cross section as can happen with through drilling, thereby lessening the chance of rotorscracking over time and heavy use.

Features : Wide aperture grooves, Zinc anti-corrosion coated castings, Special disc alloys UNIQUE to EBC, Dimple hole construction, Balanced geometry.
