The wide aperture slots in the GD Sport Rotors series have been shown to reduce brake temperatures by up to 100 degrees by drawing cooling air beneath the brake pad under load. The super silent Ultimax USR slotted series also run cooler along with the new bi-directional BSD series.

All designs offer benefits such as:

• Cooler brakes
• Resistance to cracking is possible through 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.)
• As the pad and rotor wear the slots maintain a perfectly flat and smooth pad surface and prevent rotor ribbing.

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.
