The EBC GD Sport rear rotor set for 2009–2011 Audi A4 2.0 Turbo replaces stock rear discs with OE-spec grey cast iron rotors built to production standards. These rear rotors (300mm diameter, 12mm thickness, 5 bolt holes) are solid and slotted to clear debris, reduce fade, and help brakes run cooler. Many EBC rotors are British made and undergo material and runout testing.
