• Vented rotor design to reduce heat buildup
• Black zinc-coated hat finish for corrosion resistance
• Rust resistant coating on rotor surface
• 5 bolt holes with 114.3 mm bolt circle diameter
• Nominal thickness of 22 mm with a discard thickness of 20 mm
• Outside diameter of 276 mm and overall height of 65 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor 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 in a directional pattern, which aids in removing brake dust, gases, and water from the contact area, improving braking consistency and reducing fade. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring safe and reliable use within specified wear limits.

The rotor hat is finished with a zinc black coating to provide additional protection against rust and corrosion, complementing the rust-resistant coating applied to the rotor surface. The rotor features five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 77 mm, matching the Mazda RX-7’s hub specifications. The overall height of the rotor is 65 mm, and the stud/lug hole diameter is 12.5 mm, designed to fit securely on the vehicle’s wheel hub.

About the DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine enhanced heat dissipation and improved braking surface contact. The drilled and slotted design is directional, optimizing the rotor’s ability to clear debris and maintain consistent pad contact. The black zinc finish on the rotor hat adds corrosion resistance, extending the rotor’s service life in various driving conditions.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Helps prevent brake pad glazing by maintaining a clean contact surface
• Minimizes rust and corrosion on rotor surfaces for longer durability
• Ensures proper fitment and performance on Mazda RX-7 models

Installation Notes and Tips

When installing the Dynamite Friction 633-80013L rotor on a Mazda RX-7, ensure the rotor is mounted with the directional surface pattern facing the correct rotation direction as indicated on the rotor. Verify that the rotor thickness is within the nominal and discard limits before installation. Clean the rotor surface with brake cleaner to remove any protective oils prior to mounting. Use the correct torque specifications for the 5 lug bolts to secure the rotor properly.
