Audi S4 (B9) Carbon Ceramic Brakes Upgrade

Build Configuration

This Audi S4 B9 upgrades its front brakes with Brembo BM6 calipers and STOPFLEX carbon ceramic rotors. The wheel-off view shows the front assembly clearly, while the wheel-on photos show the red caliper and drilled disc through dark multi-spoke wheels.

  • Front: Brembo BM6 6-piston calipers with STOPFLEX 380 × 34mm carbon ceramic rotors.
  • Pads: STOPFLEX carbon ceramic-compatible brake pads.

The BM6 calipers, our 380 × 34mm rotors and ceramic-compatible pads form one front-brake upgrade for the S4 B9. Our carbon-silicon-carbide rotor material is selected for high-temperature stability, while our CCB-specific pad line is developed for the ceramic friction surface. Low rotor wear and low visible dust are priorities of that friction pairing.

Carbon ceramic rotors also resist flash-rust, preserving the ceramic appearance behind the S4’s dark open-spoke wheels. Compared with like-sized iron discs, carbon ceramic construction can reduce rotating and unsprung mass at the front axle. The result is a complete BM6 solution that brings the calipers, carbon ceramic discs and CCB pads together in one clearly specified front package. Our team handles the complete upgrade specification for your car.

Send us your VIN, year, make, model and current configuration. We’ll recommend the right carbon ceramic brake package for your S4 B9.
