Currently EVERY SINGLE ROTOR sold in Europe and the UK is BRITISH MADE and a majority of the designs specific to the USA are also BRITISH made.The British foundry is constantly expanding its in house tooled range but EBC like every brake manufacturer ....does need occasionally to buy some rotors in from approved sources to complete ranges in overseas markets. None of our competitors will ever tell you where their rotors come from and we at EBC are as disappointed as the rest of the world that cost pressure means there is not ONE foundry left in the USA to supply such parts, other brake brands when asked about origin will just sidestep the question. When we do buy rotors in, they are specified, sampled, tested for element analysis, grain structure, tensile strength, hardness and optimum ductility and tested 100 piece by piece to be perfect for runout on this in house machine.\nFor FMSI Pad No. D1111\n\u003cul\u003e\n  \u003cli\u003eRemoves dirt dust and debris from braking zone\u003c\/li\u003e\n  \u003cli\u003eAnodized For Protection\/Black For Domestics\u003c\/li\u003e\n  \u003cli\u003eReduces brake fade under load and at speed\u003c\/li\u003e\n  \u003cli\u003eGreat For Truck\/SUV\/Towing\/For Sedan Use\u003c\/li\u003e\n  \u003cli\u003eAnodized For Protection\/Gold For Imports\u003c\/li\u003e\n  \u003cli\u003eWide Slots Helps Brakes Run Cooler\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBrief Description:\u003c\/strong\u003e EBC GD1421 GD Sport Front Brake Rotors are engineered for the 2004–2008 Audi S4 equipped with the 4.2L engine. Built from OE-specification gray cast iron, these performance rotors provide dependable braking control for daily driving, spirited use, towing, and demanding truck or SUV applications where applicable. The GD Sport design uses wide slots to help remove dirt, dust, and debris from the braking zone while promoting cooler brake operation.\u003c\/p\u003e\n\n\u003cp\u003eEBC manufactures many rotor designs in its own British foundry, with production components specified and tested for material composition, grain structure, tensile strength, hardness, ductility, and runout. The rotors are designed to work with applications using FMSI pad number D1111 and are suitable for drivers seeking improved resistance to brake fade under load and at speed. A protective anodized finish helps guard the rotor surfaces, with a black finish used for domestic applications and a gold finish used for import applications as applicable to the product design.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeature:\u003c\/strong\u003e Wide brake slots help evacuate friction material dust and debris while supporting cooler operating temperatures.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeature:\u003c\/strong\u003e OE-spec gray cast iron construction delivers consistent braking performance and durability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeature:\u003c\/strong\u003e Designed to reduce brake fade during repeated braking, high-speed driving, towing, and loaded conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeature:\u003c\/strong\u003e Protective anodized finish helps resist surface corrosion and supports long-term appearance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Product Specifications \u0026amp; Technical Data:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EBC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e GD1421\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e GD Sport front brake rotor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicle Application:\u003c\/strong\u003e 2004–2008 Audi S4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEngine Application:\u003c\/strong\u003e 4.2L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Compatibility:\u003c\/strong\u003e FMSI pad number D1111\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e OE-spec gray cast iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotor Design:\u003c\/strong\u003e Slotted performance design with protective anodized finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Included in the Box:\u003c\/strong\u003e One EBC GD1421 GD Sport front brake rotor.
