Enjoy improved sport braking with EBC USR Blackdash Brake Discs. Just like regular slotted discs, these degas pads for cooler braking operation and help remove dirt, brake dust, and water from the brake area. They also promote flat and parallel pad wear for consistent braking performance during the life of the discs and the pads. But what sets Blackdash discs above all other slotted discs is its multi-slot pattern. Unlike regular slots that produce air noise, Blackdash disc slots are narrower in size and are set at a progressive angle, making braking operation incredibly quiet and effective at the same time.
Specifications:
- 5 lugs
- 12.58 in. disc diameter
Features:
- Manufactured to OE specifications using high tensile strength G3000 gray cast iron
- Coated with black zinc finish
- Maintains a flat and parallel pad wear and avoids the record grooves or galling common with non-slotted rotors
Professional installation is recommended, but you can install this brake disc yourself with EBC Instructional Video P/N E35DVD083 (sold separately). Never use old brake pads with new discs. For optimal braking performance, match Blackdash discs with EBC Redstuff, Greenstuff, or Yellowstuff brake pads.
