DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide enhanced braking efficiency through a combination of drilled holes and precision slots. This design helps to reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The directional surface pattern ensures consistent pad contact and braking response, making it suitable for demanding driving conditions on Land Rover Discovery, LR4, Range Rover, and Range Rover Sport vehicles.

Detailed Product Description

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. The rotor's nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring a long service life before replacement is necessary. The rotor surface is finished plain, while the hat is coated in Geospec silver grey, providing corrosion resistance and a clean appearance. The rust resistant coating further protects the rotor from environmental damage. With a 360 mm outside diameter and 62.3 mm overall height, this rotor is engineered to meet the exact specifications required for compatible Land Rover models. The 5 bolt holes and stud/lug holes, each 15 mm in diameter with a 120 mm bolt circle diameter, ensure proper fitment and secure installation.

Applications and Problem Solving

• Replacement rotor for worn or warped disc brakes on Land Rover Discovery, LR4, Range Rover, and Range Rover Sport
• Improves braking performance by reducing heat buildup and brake fade
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Prevents rust and corrosion-related rotor damage with protective coatings
• Maintains consistent braking response under demanding driving conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27 mm before installation. Clean the rotor surface to remove any protective oils or residues prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5 bolt holes and 120 mm bolt circle diameter. Proper torque specifications should be followed to secure the rotor. Directional surface design requires correct orientation during installation to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures the 830-11011L rotor to meet strict quality standards for fitment and durability. The rust resistant coating and Geospec silver grey hat finish contribute to long-term corrosion protection. While no specific warranty information is provided, Dynamite Friction products are engineered to comply with OEM specifications for Land Rover Discovery, LR4, Range Rover, and Range Rover Sport vehicles.
