EBC GD975 3GD Series Dimpled and Slotted Sport Brake Rotor Set

The EBC GD975 is part of EBC's 3GD Series — a premium line of dimpled and slotted sport rotors precision-machined from high-quality grey iron castings. Designed for performance street driving, these rotors deliver improved cooling, consistent pad wear, and corrosion resistance in a sporty silver finish.

Wide-Aperture Slot Design:

The GD975's wide-aperture scraper slots draw cooler air directly into the brake pad and rotor contact zone — an area that can exceed 1,000°F during heavy braking. This active cooling can reduce operating temperatures by up to 200°F, significantly reducing brake fade under load and at speed.

Key Features:

• Dimple-drilled construction — EBC invented the dimple-drilled rotor design in the 1990s; blind-drilled dimples promote pad degassing without the stress cracking risk of fully through-drilled rotors
• Wide-aperture slots — full-sweep slots expel dirt, dust, debris, and water from the braking zone while maintaining flat, parallel pad wear and maximizing pad contact throughout the rotor's life
• Corrosion-resistant finish — silver anti-corrosion coating protects the rotor surface and maintains appearance over time
• OE-spec grey iron construction — cast from high-quality G3000 grey iron to OEM-equivalent specifications
• 100% quality inspected — every rotor undergoes a full runout check, metallurgy inspection, and dimensional verification before release
• R90 brake safety tested — passed European R90 brake safety standards; proven to run measurably cooler than non-slotted rotors
• Machined and finished in the UK or USA — all GD series rotors are precision machined and finished in ISO and TÜV approved EBC facilities
• Sold as a pair — includes two front rotors

Important Note on Noise: Like all slotted rotors, the GD series produces increased air noise as the rotor passes beneath the brake pads during normal driving and braking. Drivers who prefer a quieter option should consider EBC's USR Ultimax slotted rotor series, which offers similar performance with significantly reduced noise.

The EBC GD975 is an excellent upgrade for sport sedans, trucks, SUVs, and performance applications where brake fade prevention and consistent stopping power are priorities. Pair with EBC performance brake pads for best results.
