The dimple drilled rotor was invented by EBC back in the 90’s and has been imitated by many because of its ability to offer pad degassing without “Through Drilling” disc or rotor holes which has been shown to promote rotor cracks.
The wide aperture slots on the EBC units actually draw cool air under the brake pad and rotor interface and help cool the temperatures of the pad contact which can shoot up to well over 1000 degrees at the very heart of the brake pad during heavy braking and can cause brake fade or loss of brake effect.

As with the Bluestuff NDX brake pads, Orange grade pads once bedded are safe for street driving on your way to a track event. Lifetime is longer than Bluestuff grade but again must be regularly monitored especially if driving home on these brakes after track use.
