Dynamite Friction 830-80078R Disc Brake Rotor - Front Right

Front Right Drilled and Slotted Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted, part number 830-80078R, is a vented front right disc brake rotor built for Mazda applications that call for a 320 mm rotor with a 5-lug, 114.3 mm bolt circle. Its slotted X drilled surface, directional brake face, and rust resistant coating support consistent braking performance and a cleaner rotor appearance.

For Mazda CX-5, Mazda CX-9, and Mazda 6 front right brake service, 830-80078R provides the fitment and dimensions needed for direct replacement applications. The Geospec Silver Grey hat finish adds corrosion protection at the hub area, while the plain disc finish and vented construction align with everyday street use and heat management requirements.
