EBC GD538 GD Sport Front Brake Rotors for 1986–1989 Mazda RX-7

All EBC rotors are made from OE spec grey cast iron, exactly as used on new car production and as many as we have tools for are BRITISH MADE wholly in our own UK foundry. 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. For FMSI Pad No. D331

• Removes dirt dust and debris from braking zone
• Anodized For Protection/Black For Domestics
• Reduces brake fade under load and at speed
• Great For Truck/SUV/Towing/For Sedan Use
• Anodized For Protection/Gold For Imports
• Wide Slots Helps Brakes Run Cooler

Upgrade 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.

The 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.
