• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 0.87 inches (22 mm) with discard thickness at 0.79 inches (20 mm)
• Overall height of 1.91 inches (48.4 mm) for precise fitment
• Outside diameter of 12.2 inches (310 mm) suitable for specific Audi and Volkswagen models
• Five mounting bolt holes with a 4.41 inch (112 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Product Details and Specifications

The DuraGo BR900820 rotor is constructed from cast iron, providing a balance of durability and thermal conductivity essential for effective braking. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under demanding conditions. The rotor’s nominal thickness of 0.87 inches (22 mm) ensures a solid braking surface, while the discard thickness of 0.79 inches (20 mm) indicates when replacement is necessary to maintain safety and performance.

With an outside diameter of 12.2 inches (310 mm) and an overall height of 1.91 inches (48.4 mm), this rotor is engineered to fit a range of Audi and Volkswagen vehicles, including the Audi S3, TT RS Quattro, and Volkswagen Passat CC. The five mounting bolt holes with a 4.41 inch (112 mm) bolt circle diameter provide secure attachment to the hub assembly. This rotor features a conventional design without cross-drilling or slotting, and it does not include an ABS tone ring, making it compatible with vehicles that do not require this feature.

Compatible Vehicles and Applications

• Designed for Audi models such as A3 Quattro, S3, RS3, TT Quattro, TT RS Quattro, and TTS Quattro
• Compatible with Volkswagen models including Golf R, GTI, Passat, Passat CC, Atlas, Atlas Cross Sport, Tiguan, CC, and R32
• Ideal for replacing worn or damaged rotors to restore braking efficiency
• Suitable for vehicles experiencing brake noise, vibration, or reduced stopping power
• Addresses rotor wear issues such as scoring, warping, and thickness loss

Installation Notes and Tips

When installing the DuraGo BR900820 rotor, ensure the rotor surface is clean and free of any contaminants before mounting. Verify that the rotor thickness meets the minimum discard thickness specification to maintain safety. Use proper torque specifications for the mounting bolts to avoid rotor distortion. This rotor is non-directional, allowing installation on either side of the vehicle without concern for rotation direction. It is recommended to inspect brake pads and other braking components during installation for optimal system performance.
