Detailed Product Description

The 830-47021R rotor from Dynamite Friction’s DFC Geoperformance Rotor - Drilled and Slotted line is designed specifically for Chevrolet Corvette models. This rotor features a vented construction that allows air to flow through the rotor, helping to dissipate heat generated during braking. The directional slotted and drilled surface improves pad bite and helps evacuate gases, dust, and water from the braking surface, which can enhance braking consistency and reduce the risk of brake fade.

The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring a long service life before replacement is necessary. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor is coated with a rust-resistant layer to protect against environmental damage. The rotor’s dimensions include an outside diameter of 305 mm and an overall height of 55.6 mm, with a center hole diameter of 70.7 mm and five bolt holes sized at 13 mm diameter on a 120.7 mm bolt circle diameter, matching the Chevrolet Corvette’s specifications.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with vented construction. This design aims to improve braking performance by enhancing heat dissipation and maintaining cleaner rotor surfaces during operation. The directional surface pattern is engineered to optimize braking efficiency and pad contact, making these rotors suitable for performance-oriented vehicles like the Chevrolet Corvette.

Common Applications and Problem Solving

• Reduces brake fade during high-performance or spirited driving
• Improves braking response in wet or dusty conditions
• Helps prevent rotor surface glazing and pad material buildup
• Extends rotor life with rust-resistant coating and corrosion-resistant hat finish
• Maintains consistent braking performance under heavy load or repeated stops

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (18.4 mm) before installation
• Verify bolt hole pattern and diameter match Chevrolet Corvette specifications
• Clean rotor surface before installation to remove any protective coatings
• Use proper torque specifications for lug nuts to avoid rotor warping
• Inspect brake pads for wear and compatibility with drilled and slotted rotors

Quality Assurance

Dynamite Friction manufactures the 830-47021R rotor to meet OEM standards for fitment and performance on Chevrolet Corvette vehicles. The rust-resistant coating and Geospec silver grey hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and braking efficiency within the specified thickness limits.
