EBC GD7660 GD Sport Dimpled and Slotted Brake Rotor Set

The EBC GD7660 GD Sport Rotor Set delivers a proven performance upgrade over standard brake rotors with a slotted and dimple-drilled design engineered to reduce heat, improve pad wear, and maintain consistent stopping power under demanding conditions.

Wide-Aperture Cooling Slots

The signature wide-aperture full-sweep slots actively draw cool air beneath the brake pad and rotor contact surface during braking. Brake pad contact temperatures can exceed 1,000°F under hard braking — a leading cause of brake fade and reduced braking effectiveness. These slots help dissipate that heat while simultaneously evacuating dirt, dust, water, and debris from the braking zone for more consistent performance in all conditions.

Dimple-Drilled Design

EBC pioneered the dimple-drilled rotor design in the 1990s as a safer alternative to through-drilled rotors. Dimple drilling promotes brake pad outgassing and improves cooling without creating the stress fracture points associated with fully drilled-through holes — a design widely imitated but originated by EBC.

Flat and Parallel Pad Wear

One of the most important benefits of slotted rotors is their ability to maintain flat, parallel brake pad wear throughout the life of the pad set. This prevents the uneven surface grooving and galling common with plain rotors, preserving consistent pad-to-rotor contact and braking efficiency over time.

Key Features:

• Wide-aperture full-sweep slots reduce brake temperatures and prevent fade
• Dimple-drilled pattern promotes pad outgassing without risk of stress cracks
• Long-lasting corrosion-resistant Geomet black finish for durability and appearance
• Manufactured to OEM specifications from high-quality grey cast iron
• 100% machined in the UK from R90-approved blanks
• Every rotor undergoes 100% runout, metallurgy, and dimensional inspection before release
• Balanced and runout-inspected prior to shipment
• Sold as a set (pair)

The EBC GD7660 is an ideal upgrade for performance street driving, fast road use, and light towing applications. Note: slotted rotors produce increased air noise under braking — drivers preferring a quieter option should consider the EBC USR series.
