EBC Mustang EcoBoost GD Sport Slotted and Dimpled Rear Rotors (2015-2017)

Stock rear rotors on the 2015-2017 Mustang EcoBoost handle daily driving without complaint, but they were not specced for track days where heat, fade, and rotor wear become real concerns. The EBC GD Sport slotted and dimple-drilled rear rotors address all three without the cracking risk that comes from through-drilled designs.

Dimple drilling without the crack risk. EBC pioneered the dimple-drilled rotor in the 1990s as a direct answer to the structural weakness of through-drilled rotors. The dimples provide pad degassing and bite improvement while leaving the rotor face intact, eliminating the stress risers that cause conventional drilled rotors to crack under repeated thermal cycling.

Wide-aperture slots that actively manage heat and contamination. The GD series slots draw cool air into the pad-to-rotor interface, where temperatures can exceed 1,000 degrees Fahrenheit during heavy braking. That airflow pulls heat away from the contact zone, reducing the risk of brake fade. The same slots expel water, dust, mud, and debris, so the rotor surface stays clean and consistent lap after lap or corner after corner.

Third-generation corrosion protection. Every GD series rotor ships with a silver corrosion-resistant finish that keeps the rotor looking clean between drives and prevents surface rust from contaminating the braking surface during storage or wet-weather use.

Manufactured to strict dimensional standards. EBC machines these rotors from R90-approved blanks, with the majority of castings sourced from EU foundries operating under ISO and BS5750 accreditation. Every rotor receives a 100-percent runout inspection, metallurgy check, and dimensional verification before release, followed by a balance check specific to the GD sport range.
