The EBC GD Sport front rotors for 2006–2009 BMW Z4 3.0 Si are slot-and-drilled sport rotors that help remove dust and debris while improving cooling. Made to OE-spec grey iron standards, these vented rotors are anodized for protection and use wider slots to reduce fade under load. They’re a suitable upgrade for drivers seeking cooler, more consistent braking in spirited or towing scenarios.
