GiroDisc 06-08 Audi RS4 (B7) 380mm Zinc Plated Slotted Front Rotors (w/Spacers)
Direct replacement front brake rotors for the 2006-2008 Audi RS4 B7 include caliper spacers to fit over the larger 380mm diameter. These slotted rotors weigh 22.6 lbs each compared to stock 25.5 lbs reducing rotational mass for faster acceleration and sharper handling. Gain increased braking force and heat dissipation from the upgraded size and design.
Key Features
- Larger 380mm Diameter: Exceeds OEM 365mm size for stronger stopping power and higher cooling efficiency during extended track or street use.
- Weight Reduction: Each rotor at 22.6 lbs drops unsprung weight by nearly 3 lbs per side improving suspension response and acceleration.
- Premium Materials: 6061-T6 aircraft aluminum hat paired with proprietary USA-poured cast iron disc fully machined in-house for durability.
- Curved Vane Design: Racing-developed vanes pump air centrifugally through the rotor to pull away heat and resist fade.
- Floating Mount System: 12 cadmium-plated alloy steel drive pins with anti-noise spring washers ensure quiet operation self-centering and thermal expansion handling.
Product Notes
- Sold as a pair with included caliper spacers for direct OE replacement.
- Replace only the cast iron disc section as needed keeping the aluminum hat for cost savings.
- Zinc plated finish resists corrosion in harsh conditions.
Installation Notes
- Professional installation recommended.
- Bolt-on fit using provided caliper spacers no modifications required.
- Class 12.9 cap screws and hardened washers secure the floating pins.
