Audi S4: ALCON RC6 and 380mm Carbon Ceramic Front Brakes

Build Configuration

This Audi S4 upgrades its front brakes with ALCON RC6 6-piston calipers and STOPFLEX long-fiber carbon ceramic rotors. The photographs show the upgraded red calipers and drilled rotors behind silver multi-spoke wheels on a black wagon.

  • Front: ALCON RC6 6-piston calipers with STOPFLEX 380mm long-fiber carbon ceramic rotors.
  • Front wheel shown: 19-inch BBS-marked wheel with a 255/35 R19 tire.

The ALCON RC6 6-piston calipers and our 380mm long-fiber rotors form this S4’s upgraded front assembly. Continuous carbon strands provide the rotor body’s structure for strength and thermal durability. Our carbon ceramic friction material is selected for high-temperature stability, giving the caliper-and-rotor package its ceramic foundation. The red RC6 calipers and drilled discs remain visible through the silver multi-spoke wheels.

Our CCB-specific brake pad range is developed for ceramic discs, with low rotor wear and low visible dust as design priorities. Our carbon ceramic rotor faces resist flash-rust and carry a ceramic-glaze finish. Compared with like-sized iron discs, carbon ceramic construction can reduce rotating and unsprung mass at the front axle. Our professional team handles the complete RC6 brake proposal, combining the caliper hardware, long-fiber rotors and ceramic-compatible friction pairing.
