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. D331\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\u003eUpgrade the braking performance of your 1986–1989 Mazda RX-7 with EBC GD538 GD Sport Front Brake Rotors. Designed for vehicles using FMSI pad number D331, these performance rotors are engineered to improve heat management, braking consistency, and resistance to fade during demanding street, towing, truck, SUV, and sedan applications. EBC manufactures its rotors from OE-specification gray cast iron, matching the material used in original-equipment vehicle production.\u003c\/p\u003e\n\u003cp\u003eThe GD Sport design uses wide, precision-machined slots to help clear dirt, dust, and braking debris from the friction zone while promoting cooler brake operation. This design supports more consistent pad contact and helps reduce brake fade under heavy load or at higher speeds. Depending on the application and market, EBC rotors may be produced in the company’s British foundry or sourced from approved facilities that meet EBC’s requirements for material composition, grain structure, tensile strength, hardness, ductility, and runout control.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eApplication: Front brake rotor set for 1986–1989 Mazda RX-7\u003c\/li\u003e\n  \u003cli\u003eBrand: EBC\u003c\/li\u003e\n  \u003cli\u003ePart Number: GD538\u003c\/li\u003e\n  \u003cli\u003eRotor Series: GD Sport\u003c\/li\u003e\n  \u003cli\u003eVehicle Type: Mazda RX-7 with 2.4-liter or 1.3-liter rotary engine applications\u003c\/li\u003e\n  \u003cli\u003ePad Compatibility: FMSI pad number D331\u003c\/li\u003e\n  \u003cli\u003eMaterial: OE-specification gray cast iron\u003c\/li\u003e\n  \u003cli\u003eDesign: Vented, wide-slot performance rotor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEach rotor is inspected and tested to support reliable dimensional accuracy, balanced braking, and consistent performance.
