EBC Turbo Groove Discs have a wider slot which actually draws cool air across the pad surface keeping pads and rotors cooler.
Turbo Groove Discs also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale and become ineffective in our opinion.
EBC discs use blind drilled holes to 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 rotors cracking over time and heavy use.
We recommend the use of EBC RedStuff pads with these disks.
