DFC Hi-Carbon Alloy Geomet Coated Rear Brake Rotor - Select Audi & Volkswagen 2006-2026 (900-74030)

Fits select 2006-2026 Audi A3, Q3, RS3, S3, TT and Volkswagen Arteon, Atlas, CC, Golf R, GTI, and Passat.

The DFC Hi-Carbon Alloy Geomet Coated Rear Brake Rotor is engineered for drivers demanding superior thermal stability and long-term durability. Constructed from premium G3000/G11H18 high-carbon iron castings, these rotors are designed to handle the increased heat loads of modern braking systems while minimizing noise and vibration. The specialized high-carbon alloy composition provides better heat dissipation and damping characteristics compared to standard rotors.

Each rotor features a Geomet coating to provide exceptional corrosion resistance, ensuring the hub and vanes remain protected in harsh environments. To ensure a smooth, vibration-free experience, every unit is 100% precision mill-balanced and finished with a 16 RMS fine-turned surface to optimize initial pad break-in. This rotor maintains strict tolerances for thickness variation and lateral runout, providing a high-performance alternative to OE components.
