EBC GD7669 GD Sport Dimpled and Slotted Brake Rotor Set

The EBC GD7669 is part of EBC Brakes' industry-leading 3GD Sport Rotor series — a dimpled and slotted brake disc upgrade engineered for drivers who demand superior thermal management and consistent stopping power. Sold as a set, these rotors are an ideal performance upgrade for street-driven cars, trucks, and SUVs, including applications that see spirited driving, towing, or frequent heavy braking.

Wide Aperture Cooling Slots

The defining feature of the GD Sport series is its wide aperture slot design, which actively draws cool air beneath the brake pad and rotor interface during braking. Brake pad contact temperatures can exceed 1,000°F under hard use, and these slots have been shown to reduce brake temperatures by up to 100°F — directly combating brake fade and preserving consistent pedal feel. The slots run full-width to the outer edge of the rotor, ensuring water, mud, dirt, and debris are continuously expelled from the braking zone rather than pocketed at the rotor edge.

Dimple Drilling — No Stress Cracks

EBC pioneered the dimple-drilled rotor design in the 1990s. Unlike through-drilled rotors, which are prone to stress cracking over time, EBC's dimple pattern provides the same pad outgassing and cooling benefits without compromising structural integrity. The dimpled surface also promotes even pad wear and maintains a flat, parallel pad contact surface throughout the life of the brake set.

Corrosion-Resistant Finish

Every GD Sport rotor is finished with EBC's long-lasting Thermic Black or Nitrotherm™ corrosion-resistant coating, protecting the non-swept areas of the rotor — including the hat, vents, and hub — from rust and deterioration.

Quality Casting & Precision Machining

EBC rotors are cast from high-quality G3000 or G3500 high-carbon grey iron to OEM-equivalent specifications. All rotors in the GD Sport line are 100% precision machined, balanced, and runout-inspected in either the UK or USA facilities before release. When castings are sourced externally, they undergo rigorous testing including element analysis, grain structure evaluation, tensile strength measurement, hardness testing, and ductility checks — with 100% piece-by-piece runout inspection.

Key Features:

• Sold as a set
• Wide aperture full-sweep slots reduce brake temperatures and prevent brake fade
• Dimple-drilled design promotes pad outgassing without risk of stress cracks
• Thermic Black / Nitrotherm™ corrosion-resistant coating on non-swept surfaces
• Cast from high-quality G3000/G3500 high-carbon grey iron
• 100% runout, metallurgy, and dimensional inspection before release
• Precision machined and balanced in the UK or USA
• Maintains flat, parallel pad wear surface throughout rotor life
• Expels dirt, dust, water, and debris from the braking zone
• Direct OEM replacement fitment — no modifications required

For a quieter slotted rotor with similar performance characteristics, EBC also offers the USR Sport Rotor series. The GD/3GD series is the preferred choice for trucks, SUVs, towing applications, and performance street vehicles where maximum cooling is the priority.
