Dynamite Friction 830-79003L Disc Brake Rotor - Rear Left

Overview of Dynamite Friction DFC Geoperformance Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted (part number 830-79003L) is engineered to provide reliable braking performance for vehicles requiring a 320mm outside diameter rotor with a 5-lug bolt pattern. Designed with a directional slotted and drilled surface, this rotor enhances heat dissipation and brake pad bite for improved stopping power.

• Disc brake rotor with drilled and slotted surface for enhanced cooling
• Nominal thickness of 22mm with a discard thickness of 20mm
• Rust resistant coating to reduce corrosion and extend rotor life
• Geospec silver grey hat finish for durability and corrosion resistance
• 5 bolt holes with a bolt circle diameter of 114.3mm
• Directional brake surface optimized for specific rotation
• Center hole diameter of 67mm and rotor height of 67.1mm

Detailed Product Description

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering rotors with enhanced thermal management and surface design. The drilled holes and precision slots help to evacuate gases, dust, and water from the braking surface, reducing brake fade and maintaining consistent performance under demanding conditions. The directional surface design ensures optimal contact with brake pads, improving braking efficiency and pedal feel.

The rotor’s nominal thickness of 22mm and discard thickness of 20mm provide a clear service limit to maintain safety and performance. The rust resistant coating and Geospec silver grey hat finish protect the rotor from corrosion, which is especially beneficial for vehicles operating in humid or salty environments. With a 5-lug bolt pattern and 114.3mm bolt circle diameter, this rotor is compatible with various makes and models requiring these specifications.

Applications and Problem Solving

• Reduces brake fade during heavy braking or towing
• Improves heat dissipation for consistent braking performance
• Minimizes corrosion-related rotor damage
• Enhances brake pad bite and reduces noise
• Suitable for vehicles requiring a 320mm diameter, 5-lug rotor with directional surface

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s wheel rotation. Verify the bolt pattern matches the vehicle’s hub (5 bolts, 114.3mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 20mm. Clean the rotor surface to remove any protective coatings or residues before mounting to ensure optimal brake pad contact.

Quality Assurance

Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet industry standards for durability and performance. The rust resistant coating and precision machining contribute to long service life. Warranty information is available through the manufacturer and should be confirmed at the time of purchase.
