EBC GD1308 3GD Series Sport Slotted Dimpled Vented Brake Rotors Pair

The EBC GD1308 is part of the 3GD Series Sport Rotor line — a third-generation, performance-engineered brake disc featuring a proprietary combination of wide-aperture slots and blind-drilled dimples. Sold as a pair, these vented rotors deliver measurably cooler braking temperatures, reduced brake fade, and consistent pad contact for drivers who demand more from their braking system.

Key Features:

• Wide-Aperture Scraper Slots: Full-sweep slots actively draw cool air into the pad-rotor interface, helping manage temperatures that can exceed 1,000°F during heavy braking and preventing brake fade.
• Blind-Drilled Dimples: EBC pioneered the dimple-drilled rotor design in the 1990s — providing the pad degassing benefits of through-drilled rotors without the stress crack risk associated with full through-drilling.
• Vented Construction: Internal venting further aids heat dissipation for sustained performance under demanding driving conditions.
• Flat and Parallel Pad Wear: Slot geometry helps maintain even pad contact, reducing uneven wear and extending pad life.
• Dirt, Dust, and Gas Expulsion: Full-sweep slots clear debris, water, and brake gases from the rotor surface for consistent, reliable stopping power.
• Silver Anti-Corrosion Finish: A durable corrosion-resistant coating protects the rotor surface and provides an aggressive sport appearance.
• 10.90 in. Rotor Diameter: Precision-machined to OE dimensions for direct-fit installation using stock calipers.
• European R90 Certified: GD Series rotors have passed European R90 brake safety standards and have been shown to run up to 100°F cooler than non-slotted rotors.
• 100% Runout Inspected: Every rotor is individually inspected for runout prior to shipment, ensuring zero distortion out of the box.

Note on Directional Installation: GD1308 rotors are directional — the sweeping grooves and dimple pattern must point toward the rear of the vehicle when installed. Note on Brake Noise: As with all slotted rotors, some increase in air noise under normal driving and braking should be expected. Drivers preferring a quieter option may wish to consider EBC's USR Sport Rotor series.

EBC GD Series sport rotors are precision-machined in ISO and TÜV approved facilities in the UK and USA, with all USA sport rotors slotted at EBC's Las Vegas machining facility. Each rotor undergoes strict metallurgical testing, dimensional checks, and 100% individual runout inspection before release.
