EBC GD1066 GD Sport Dimpled and Slotted Disc Brake Rotors

The EBC GD1066 GD Sport Brake Rotors are a third-generation performance disc brake rotor featuring wide-aperture slots and dimple drilling for superior cooling, reduced brake fade, and consistent stopping power. Ideal for fast street cars, trucks, SUVs, and 4x4s seeking a meaningful upgrade over standard OEM rotors.

Wide-Aperture Slot Technology:

• Full-sweep slots are machined to the outer edge of the rotor, actively drawing cool air beneath the brake pad during braking to reduce interface temperatures — which can exceed 1,000°F under heavy use
• Slots help expel dirt, dust, mud, and water from the braking zone for consistent pad-to-rotor contact
• Maintains a flat, parallel pad surface over the full life of the brake pad, preventing rotor ribbing and uneven wear

Dimple-Drilled Design:

• EBC pioneered the dimple-drilled rotor in the 1990s as a safer alternative to through-drilled rotors
• Dimples allow for brake pad outgassing without the stress crack risks associated with through-drilled holes

Construction and Quality:

• Cast from high-quality G3000 grey iron to OE specifications for strength, ductility, and thermal stability
• 100% machined and finished in the UK or USA; all sport rotors are balanced and runout-inspected before release
• Every rotor undergoes a 100% dimensional, metallurgy, and runout check prior to shipment
• Long-lasting corrosion-resistant finish applied via the thermic black or NITROTHERM™ process for durability and appearance

The EBC GD1066 is a direct-fit replacement rotor that installs like stock while delivering noticeably improved braking performance.
