Carbon-Ceramic Brake Disc – Ultra-High Performance Rotor for Audi S/RS & Exotic Models
(Engineered for road & track, 70 % lighter than cast iron, lifetime warp-free)

1. Material System
   • 3D-carbon fiber preform + SiC ceramic matrix (C/SiC)
   • Surface hardness: 2 200 HV10 (Rockwell HRA 92)
   • Thermal limit: 1 650 °C (no structural fade)

2. Weight Savings
   • Front Ø420 mm disc: 6.1 kg vs 18.4 kg iron (–67 %)
   • Un-sprung mass reduction per axle: ≈ 24 kg (52.9 lb)

3. Thermal & Fade Performance
   • Max working temp: 1 000 °C continuous / 1 650 °C peak
   • Heat-soak delta at 0.9 g decel 200→50 km/h: ΔT 310 °C vs 520 °C iron
   • Fade index (SAE J2784): <3 % after 15 high-speed stops from 230 km/h

4. Friction & Wear
   • Nominal μ (hot): 0.48–0.52 with performance pad compound
   • Wear rate: <0.06 mm per 5 000 km street use; <0.25 mm per 24 h endurance race
   • Disc life expectancy: >300 000 km road / 10 000 km full-race

5. Geometry & Tolerances
   • Dimensional tolerance: ±0.015 mm radial run-out, ±0.005 mm thickness variation
   • Disc thickness variation (DTV) after 1 000 thermo-cycles: <0.010 mm
   • Balancing grade: G2.5 @ 8 000 rpm (OEM spec G6.3)

6. Ventilation & Cooling
   • Internal radial+pillared vent array; 120 air channels
   • Heat-transfer coefficient h↑ 35 % vs OEM carbon-ceramic

7. Corrosion & Environment
   • 100 % oxidation-free ceramic surface; no rust, no judder
   • Salt-spray ASTM B117: 1 000 h zero mass loss
   • Acoustic damping layer reduces squeal by 12 dB(A)

8. Fitment & Compatibility
   • Direct plug-and-play for:
   – Audi RS6/RS7 (C7/C8) 420 mm front, 370 mm rear
   – Audi R8 2nd-gen (4S) 380 mm/356 mm
   – Bentley Continental GT3-R (shared platform)
   • Includes billet 7075-T6 hard-anodized hat with 10.9 grade NAS bolts
   • ABS/ESC calibration: identical polar moment—no reprogramming

9. Certification & Warranty
   • TÜV/ABE certified; meets ECE R90 & SAE J2928 carbon-ceramic protocol
   • 5-year unlimited-mileage structural warranty; wear items excluded

10. In the Box
    • 1× carbon-ceramic disc (hat pre-assembled)
    • 2× high-temp ceramic brake-paste sachets
    • Torque sheet & bed-in procedure (QR code video)
