• Vented rotor design to reduce brake fade under heavy use
• Rust-resistant zinc black hat finish for extended corrosion protection
• Nominal thickness of 30 mm with a discard thickness of 27 mm
• Fits vehicles with 5 bolt holes and 112 mm bolt circle diameter
• Outside diameter of 340 mm and overall height of approximately 50 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented design that promotes superior cooling during braking, reducing the risk of warping and brake fade. The rotor features a directional surface pattern combining drilled holes and slots, which helps evacuate gases, dust, and water for consistent brake pad contact. The zinc black finish on the rotor hat provides a rust-resistant coating, enhancing longevity in various driving conditions.

With a nominal thickness of 30 mm and a discard thickness of 27 mm, this rotor maintains structural integrity while allowing for safe wear limits. The rotor’s 5 bolt holes and 112 mm bolt circle diameter ensure compatibility with specific Audi and Volkswagen models. The center hole diameter measures 65 mm, and the stud/lug hole diameter is 15.2 mm, matching factory specifications for a precise fit.

Compatible Vehicles and Applications

This brake rotor is compatible with a range of Audi and Volkswagen vehicles, including:

• Audi A3 Quattro, S3, TTS Quattro
• Volkswagen Golf R, GTI, Jetta, Tiguan, Tiguan Limited, Arteon, CC

It is designed to replace worn or damaged rotors, restoring braking efficiency and safety for these models.

Common Issues Addressed by This Rotor

• Brake fade caused by overheating during aggressive driving or towing
• Uneven rotor wear leading to brake pulsation or noise
• Corrosion and rust buildup reducing rotor lifespan
• Reduced braking performance due to glazed or warped rotors
• Inconsistent brake pad contact from surface contamination

Installation Notes and Tips

Ensure the rotor is installed on vehicles with matching bolt pattern and dimensions. Clean the rotor surface before installation to remove any protective coatings or residues. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Verify torque specifications for lug nuts and bolts according to manufacturer guidelines.
