EBC GD Sport slotted front rotors for 1986–1991 Porsche 928 5.0 are manufactured from OE-spec grey cast iron and produced largely in EBC’s UK foundry. These vented, slotted rotors are specified to exact dimensions (304mm diameter, 32mm thick) and reduce dust and debris in the braking zone. Wide slots help brakes run cooler while anodized finishes provide extra protection for operation under load.
