Audi RS3 / S3 (8V) Sedan & Sportback Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2015-2020 Audi RS3 / S3 (8V) Sedan & Sportback Carbon Ceramic Brake Kits
The 8V RS3/S3 sits on the MQB compact platform, but RS3 buyers usually care about repeated hard-use confidence while S3 buyers lean more toward sharp street feel with less weight and dust. This row has real front-size split confusion—S3 340mm, RS3 370mm steel, and RS3 380mm carbon ceramic—so correct kit selection matters more than generic platform matching.
- Body style: Sedan & Sportback
- Front rotor reference: RS3: 370mm, 380mm (CCB); S3: 340mm
- Rear rotor reference: RS3: 310mm; S3: 310mm
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.
340mm suits S3 street cars wanting a lighter, cleaner package without oversizing the setup.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
370mm fits RS3 owners who want strong fast-road and occasional hard-use capacity with easier wheel compatibility than larger conversions.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
380mm is the RS3-focused choice when repeated high-speed stops and maximum thermal headroom are the priority.

FAQ
Can I upgrade my Audi RS3 or S3 (8V) to a StopFlex carbon ceramic brake kit while keeping the factory calipers, or is it better with aftermarket calipers?
On this 8V platform, the answer depends on your exact front brake size and intended use. Factory-caliper-based setups can work when the kit is designed around that caliper, but frequent hard-use buyers usually choose a matched aftermarket caliper package for cleaner fitment and better thermal control.
Which StopFlex carbon ceramic brake size is the right choice for my exact Audi RS3 / S3 (8V) setup?
For this row, S3 starts at 340mm front, while RS3 commonly means 370mm steel or 380mm carbon ceramic front, so you should order by the car’s actual current brake package, not just by model name. If your goal is mainly street use, stay close to the correct factory envelope; if you run repeated high-speed sessions, the larger RS3-oriented setup is the safer buy.
Is a StopFlex carbon ceramic brake kit on the Audi RS3 / S3 (8V) still a good daily-driver choice, especially for cold first stops?
Yes, if your car is mostly street-driven and you want lower dust and less rotating mass, it can make sense. The main buyer check is whether you are comfortable with slightly different first-stop feel when cold versus a conventional iron setup, because daily smoothness expectations vary owner to owner.
For my Audi RS3 / S3 (8V), do I need extra cooling or other heat-management changes with a StopFlex carbon ceramic brake kit for prolonged hard use?
If the car sees repeated canyon runs, autobahn-style speed, or track sessions, cooling becomes part of the decision on this chassis. The bigger RS3-oriented setups give more heat margin, but serious hard-use owners should still think about airflow, pad choice, and session length before ordering.
