Choose the complete rotor design and pad combination for the job.Replacement Rotors and Corrosion-Protection ChoicesBrembo UV-coated, DFC coated and PowerStop replacement references offer different application-specific service options. Compare the exact diameter, thickness, mounting dimensions and factory brake package alongside the stated coating.A smooth friction face and a corrosion-resistant coating describe separate features. Internal venting is another part of the construction. Choose the actual specification rather than assuming a plain rotor alone guarantees the quietest brakes or least dust; pads and installation also affect those characteristics.Drilled, Slotted and EB...

This collection includes vehicle-specific and motorsport braking components from DBA, EBC Brakes Racing, GiroDisc, Rotora, Wilwood, and other performance brake manufacturers for street-performance, track, racing, and high-output applications. Two-Piece Performance Brake Rotors A two-piece brake rotor separates the iron friction ring from the center hat. The components are connected using application-specific drive pins, bobbins, bolts, or other mounting hardware. Many systems use an aluminum hat to reduce weight and limit heat transfer toward the hub compared with a similarly sized one-piece iron rotor. Construction varies significantly between manufacturers. Some products are fixed two-piece assemblies, while others are fully floating or semi-floating designs that allow controlled movement as the friction ring expands under heat. The terms ...
