• Compatible with Chevrolet Corvette 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
• Nominal thickness of 20 mm with discard thickness at 18.4 mm
• Five bolt holes with 13 mm diameter and 120.7 mm bolt circle diameter
• Overall diameter of 305 mm and height of 50 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 surfaces, effectively reducing heat and minimizing brake fade during extended use. The rotor's surface is both drilled and slotted, which helps evacuate gases, dust, and water from the braking surface, improving pad contact and braking consistency. The directional pattern ensures optimal performance when installed correctly.

The rotor features a nominal thickness of 20 mm and a discard thickness of 18.4 mm, providing a clear maintenance threshold for safe operation. The hat section is finished with a zinc black coating to resist rust and corrosion, extending the rotor's service life. With five bolt holes measuring 13 mm in diameter and a bolt circle diameter of 120.7 mm, this rotor is designed to fit securely on the Chevrolet Corvette hub assembly. The overall diameter of 305 mm and height of 50 mm align with factory specifications for proper fitment.

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 delivering rotors that combine enhanced cooling features with corrosion resistance. This product line is tailored for performance-oriented vehicles like the Chevrolet Corvette, where heat management and rotor durability are critical. The drilled and slotted design improves braking efficiency while the black zinc coating on the hat section helps protect against environmental wear.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat during aggressive driving
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains consistent braking performance under high-stress conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify that the bolt hole pattern and center hole diameter (70.7 mm) match the vehicle hub specifications. It is recommended to measure the rotor thickness before installation to confirm it meets the nominal thickness of 20 mm and is above the discard thickness of 18.4 mm. Proper torque specifications should be followed when securing the rotor to the hub.

Quality Assurance and Warranty

Dynamite Friction manufactures the 633-47022L rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant zinc black coating on the hat section adds durability against corrosion. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliable performance on Chevrolet Corvette vehicles.
