EBC GD7521 3GD Sport Dimpled and Slotted Brake Rotors Front

The EBC GD7521 3GD Series Sport Rotors deliver enhanced braking performance for trucks, SUVs, and performance vehicles. This 2-rotor set features EBC's innovative combination of wide aperture slots and dimple drilling, engineered to provide superior cooling and durability under demanding driving conditions including performance street driving, towing, hauling, and 4x4 use.

Advanced Cooling Technology:

• Wide aperture slots draw cool air into the braking contact area, reducing temperatures by up to 200 degrees to prevent brake fade during heavy use
• Dimple drilling avoids stress cracks common with traditional drilled rotors while allowing brake pads to degas
• Wider vented aperture allows air to pass between both rotor sides for even heat expansion and minimized warpage
• Slots maintain flat, parallel pad wear and clear dust, dirt, and debris from the rotor surface

Premium Construction:

• Manufactured from OE-spec grey cast iron for optimal strength and durability
• Precision CNC machined to tolerances of less than 0.05 millimeters
• Cast to high metal strength rating of 150 newton meters
• Corrosion-resistant finish on non-contact areas for long-lasting appearance
• 321mm diameter, 29.9mm thick vented design with 5 bolt holes and 67.4mm center bore

What's Included: 2 front brake rotors (GD7521). EBC recommends a 500-mile break-in period with moderate braking application. These rotors are designed for use with EBC Greenstuff, Yellowstuff, or Redstuff brake pads for optimal performance. Note: Some wind noise may be observed during heavy braking, which is normal for slotted rotor designs.
