Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced surface treatments and structural designs to meet the demands of performance and daily driving. This rotor features a vented design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The drilled and slotted surface is directional, meaning it is optimized for a specific rotation direction to maximize water, gas, and dust evacuation from the braking surface.

The rotor's hat is coated with a zinc silver finish to resist corrosion, extending the rotor's service life. With a nominal thickness of 28mm and a discard thickness of 26mm, this rotor maintains safety standards for wear limits. The 5-bolt hole configuration with a 130mm bolt circle diameter and 15.2mm stud hole diameter ensures compatibility with the specified vehicle models.

Applications and Problem Solving

• Replaces worn or warped rotors on Audi Q7, Porsche Cayenne, and Volkswagen Touareg
• Improves braking performance by reducing heat buildup and brake fade
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Resists rust and corrosion for longer service intervals
• Enhances wet weather braking with directional drilled and slotted design

Installation Notes and Tips

• Ensure rotor direction matches the vehicle’s rotation for proper performance
• Check rotor thickness before installation; replace if below discard thickness of 26mm
• Use proper torque specifications on the 5 lug bolts to avoid warping
• Inspect brake pads for wear and replace if necessary during rotor installation
• Clean rotor surface with brake cleaner before mounting to remove any protective coatings
