• Compatible with Mazda Miata vehicles
• Directional drilled and slotted surface for improved brake pad contact
• Vented rotor design for efficient heat dissipation
• Rust-resistant zinc silver hat finish
• Nominal thickness of 20 mm with discard thickness at 18 mm
• Four bolt holes with 100 mm bolt circle diameter
• Overall diameter of 255 mm and height of 45 mm

Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is designed with a vented rotor type that helps reduce brake fade by allowing air to flow through the rotor during operation. The rotor surface is both drilled and slotted in a directional pattern, which aids in removing brake dust, gases, and water from the contact surface, improving braking consistency. The rotor has a plain disc finish and a zinc silver coating on the hat to resist corrosion and extend service life. With a nominal thickness of 20 mm and a discard thickness of 18 mm, this rotor meets precise wear limits for safe operation. The rotor features four bolt holes and lug holes, each with a 13 mm diameter, arranged on a 100 mm bolt circle diameter, ensuring proper fitment on the Mazda Miata hub. The center hole diameter is 55 mm, and the overall height is 45 mm, matching OEM specifications.
