Overview of Dynamite Friction DFC Brake Rotor

The Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black (part number 633-80022L) is engineered for Mazda Miata models requiring reliable braking performance. This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with Mazda Miata vehicles
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Black zinc-coated hat finish for corrosion resistance
• Rust resistant coating on rotor surface
• 4 bolt holes with 100mm bolt circle diameter
• Nominal thickness of 18mm and discard thickness of 16mm
• Outside diameter of 235mm and overall height of 45mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is constructed with a vented design that allows air to flow between the rotor faces, helping to dissipate heat more effectively during braking. The rotor surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving brake pad bite and reducing fade. The directional pattern ensures optimal performance when installed correctly according to the rotation direction.

The rotor’s hat is finished with a zinc black coating, providing additional protection against rust and corrosion, which is further enhanced by the rust-resistant coating applied to the rotor surface. With a nominal thickness of 18mm and a discard thickness of 16mm, this rotor meets the necessary specifications for safe and effective braking. The 4-bolt hole configuration with a 100mm bolt circle diameter matches the Mazda Miata’s hub pattern, ensuring proper fitment.
