Audi RS5 / S5 (B8) Sportback, Coupe & Cabriolet Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2010-2016 Audi RS5 / S5 (B8) Sportback, Coupe & Cabriolet Carbon Ceramic Brake Kits
The B8 RS5/S5 mixes real GT weight and speed with daily-road use, so buyers usually want a brake upgrade that cuts unsprung mass without making the car annoying in traffic. On this platform, the main confusion is RS5 365mm steel vs 380mm ceramic sizing, plus wheel and caliper compatibility when upgrading from S5 hardware.
- Body style: Sportback, Coupe & Cabriolet
- Front rotor reference: RS5: 365mm, 380mm (CCB); S5: 345mm
- Rear rotor reference: RS5: 330mm; S5: 330mm
This is an OEM-size replacement kit. The rotors are built to the factory rotor spec and install with the factory caliper when the front caliper is a fixed design and the rotor spec matches. The included pad shape matches the OEM pad shape. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, provide the exact caliper model and StopFlex can supply the matching pad shape. Direct replacement is not confirmed if the front caliper is floating, or if the car already runs a non-OEM-offset rotor and the actual rotor dimensions cannot be supplied.
Why StopFlex CCB
Lightweight
Half the Weight, Sharper Handling. StopFlex carbon-ceramic rotors shed roughly half the mass of equivalent iron discs. This massive drop in unsprung weight instantly transforms your chassis, delivering sharper turn-in response and a significantly more refined road feel.
High-Temp Resistance
Minimal Brake Fade at 900°C (1652°F). While traditional iron rotors severely fade under heavy track loads, our CCB matrix holds a stable 0.30μ friction coefficient even at 900°C (1652°F). You get consistent, predictable stopping power when things get dangerously hot.
Corrosion Resistance
100% Rust-Free Durability. Say goodbye to flash rust after a car wash or heavy rain. The carbon-silicon carbide material is naturally impervious to corrosion, ensuring your brake rotors look completely clean and pristine no matter the weather conditions.
Long Lifespan
250,000+ km (155,000+ mi) Lifespan. Iron rotors typically require replacement around 100,000 km (62,000 mi). In normal street driving conditions, a StopFlex CCB rotor can easily last 250,000 to 300,000 km (155,000 to 186,000 mi), effectively outlasting the vehicle itself.
Ultra-Low Dust
Ultra-Low Visible Brake Dust. Heavy black dust destroying your wheel finish is a thing of the past. When paired with our matched StopFlex pads, these rotors generate virtually zero visible brake dust, keeping your premium wheels spotless for much longer.
Premium Visual Finish
Premium Mirror-Like Finish. StopFlex utilizes a patented ceramic formula that cures with a distinct crackle pattern. The surface is machined dead-smooth for high reflectivity, providing a premium aesthetic behind open wheels under the right lighting.
High Normal-Temp Friction
Strong Initial Bite (0.40μ+). With matched StopFlex pads, normal-temperature friction can exceed 0.40μ for a firmer pedal feel and strong initial bite.
Long-Fiber Construction
Continuous Long-Fiber Strength. StopFlex utilizes a continuous long-fiber 3D matrix. This structure is significantly stronger and offers higher thermal conductivity than standard chopped-fiber OEM CCM discs.
Cold First-Stop Confidence
Reliable Cold-Bite at -20°C (-4°F). Coated street rotors still deliver normal first-stop braking at -20°C (-4°F). Uncoated motorsport rotors are the exception.
Important heat note
Carbon ceramic does not shed heat as fast as steel. Long hard driving can heat-soak the rest of the brake system, including fluid, seals, and nearby parts. Unless the car already has strong brake cooling, or you plan to upgrade brake cooling, prolonged aggressive driving is not recommended.
Rotor options

Street Spec
Ceramic coating + cross-drilled face + large cooling channels.
Street: best for daily-driven S5 and RS5 owners who want the weight and dust reduction benefits without overbuilding the car.

Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
Trackday: the 380mm front setup suits heavier, faster B8 cars that see repeated canyon or occasional circuit abuse.

Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
Motorsport: choose the largest thermal-capacity setup that fits your wheel and caliper package if the car does sustained hard lapping.

FAQ
Will a StopFlex carbon ceramic brake kit for my Audi RS5 or S5 (B8) work with the factory calipers, or do I need aftermarket calipers?
That depends on your starting point. S5 and RS5 front hardware are not the same, so caliper compatibility must be matched to your exact spindle and intended rotor size; if you already run an aftermarket BBK, StopFlex fitment needs that caliper model confirmed before order.
Which StopFlex size is correct for my Audi RS5 or S5 (B8): S5 345mm, RS5 365mm, or RS5 380mm?
Use your car's current brake package as the starting point, not just the model badge. S5 owners usually choose a kit built around the 345mm baseline or a full front upgrade path, while RS5 owners need to confirm whether the car is the 365mm steel setup or the 380mm ceramic-size configuration before ordering.
Is a StopFlex carbon ceramic brake kit on the Audi RS5 or S5 (B8) still good for street use, cold mornings, and daily driving?
Yes, that is a common reason B8 owners look at this upgrade. The key is choosing a street-biased setup and pad pairing, so first-stop behavior stays predictable rather than chasing a track-only feel.
Does my Audi RS5 or S5 (B8) need extra cooling if I upgrade to a StopFlex carbon ceramic brake kit and drive it hard for long periods?
For fast road use, many cars do fine with the kit alone if the rest of the system is healthy. For repeated hard sessions in a heavy B8 chassis, added airflow, proper fluid, and realistic wheel-clearance planning matter if you want consistent pedal feel and heat control.
