EBC GD7649 GD Sport Dimpled and Slotted Brake Rotor Set

The EBC GD7649 GD Sport Rotors are a third-generation performance brake rotor set engineered for drivers who demand superior stopping power and thermal management. Featuring wide-aperture slots and blind-drilled dimples, these rotors are designed to draw cool air beneath the brake pad interface and actively reduce braking temperatures — helping prevent the brake fade that can occur during aggressive driving, towing, or hauling.

Wide-Aperture Slot Technology:

• Full-sweep slots are machined to the rotor's outer edge to continuously expel dirt, dust, water, and debris from the braking zone
• Slots draw cooling air beneath the brake pad contact surface, reducing pad-rotor interface temperatures that can exceed 1,000°F under hard braking
• Slot design maintains a flat and parallel pad surface throughout pad life, preventing uneven wear and rotor ribbing

Dimple-Drilled Design:

• Blind-drilled dimples allow brake pad gases to escape (degassing) without the structural risks of through-drilled holes
• Through-drilling has been shown to promote stress cracks; EBC's dimple pattern delivers outgassing benefits with a higher stress-handling capacity

Quality Construction:

• Cast from high-quality G3000/G3500 high-carbon grey iron to OEM specifications
• 100% precision machined, balanced, and runout-inspected before release
• Every rotor undergoes a 100% runout, metallurgy, and dimensional check
• Finished in a long-lasting Thermic Black corrosion-resistant coating that protects off-brake areas, hub, and non-swept surfaces
• Sold as a set (pair)

The EBC GD Sport series is an ideal upgrade for performance street vehicles, trucks, and SUVs seeking improved braking consistency and reduced fade. For a quieter slotted rotor option, EBC's USR series offers comparable performance with reduced air noise.
