Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is designed with a vented rotor type to improve heat dissipation during braking, reducing the risk of brake fade. The rotor’s surface combines drilled holes and slots, which help evacuate gases, dust, and water, maintaining consistent braking performance under various conditions. The rotor has a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring durability and safety throughout its service life.

Its outside diameter measures 330 mm, with an overall height of 66 mm, fitting precisely on Jaguar XJR and XKR models. The rotor features a zinc silver hat finish that provides corrosion resistance, complemented by a rust-resistant coating on the disc surface. The 5 bolt holes, each 13.3 mm in diameter, are arranged on a 120.7 mm bolt circle diameter, matching the factory specifications for secure installation.

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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with corrosion-resistant finishes. This product line is designed to offer improved braking response and durability, particularly for performance-oriented vehicles like the Jaguar XJR and XKR. The directional surface pattern enhances water and debris evacuation, contributing to consistent brake pad contact and reduced noise.

Applications and Problem Solving

• Restores braking efficiency on Jaguar XJR and XKR models with worn or damaged rotors
• Reduces brake fade during aggressive driving or heavy braking conditions
• Improves heat dissipation to extend brake component life
• Minimizes rust and corrosion on rotor surfaces for longer service intervals
• Enhances braking consistency in wet or dusty environments

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 26 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 120.7 mm bolt circle diameter specific to Jaguar XJR and XKR models. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
