Keep your brake system cool with EBC 3GD Sport Series Brake Discs. These discs have wide aperture slots that draw cool air into the braking contact area, thereby reducing excess heat and preventing brake fade. During wet conditions, the slots help wick water away from the rotors while removing dirt, dust, debris, and gases created by heavy braking. Moreover, the slots maintain flat and parallel pad wear, keeping optimum pad contact throughout the life of the discs and pads. And, unlike other slotted discs that produce a lot of air noise, 3GD Sport Series Brake Discs only have three slots, making them more pleasant to the ear.
Specifications:
- 5 x 115 mm bolt pattern
- 12.6 in. disc diameter
Features:
- Made from precision machined, high quality gray iron that went through extensive testing and rigorous quality control
- Dimple drilled to avoid stress cracks
- Slotted to avoid the record grooves or galling common with non-slotted rotors
- New black anodized EBC finish provides great looks whilst preventing corrosion
These discs are ideal for use with EBC upgrade sport pads. Install them yourself with EBC Instructional Video P/N E35DVD083 (sold separately).
