The EBC GD Sport front slotted rotor set for 2009–2011 Audi A4 2.0 Turbo replaces stock discs with OE-spec grey cast iron rotors built to production standards. These vented, slotted front rotors (320mm diameter, 30mm thickness, 5 bolt holes) help evacuate dust and debris, reduce fade under load, and run cooler. Many EBC rotors are British made and tested for material and runout quality.
