Audi R8 (4S) Coupe & Spyder Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2016-2024 Audi R8 (4S) Coupe & Spyder Carbon Ceramic Brake Kits
The Audi R8 4S is a mid-engine V10 supercar that blends real road manners with serious speed, in both Coupe and Spyder form. Buyers usually want lower unsprung mass and stronger repeat-stop confidence without upsetting the R8’s factory balance or daily drivability.
- Body style: Coupe & Spyder
- Front rotor reference: R8: 365mm, 380mm (CCB)
- Rear rotor reference: R8: 356mm
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.
- Confirm whether your car is the 365mm steel setup or 380mm factory ceramic setup before ordering.
- Factory caliper compatibility matters on the R8 4S, especially when moving from steel to a larger ceramic package.
- Coupe and Spyder owners should choose based on real use: fast-road weight reduction or repeated high-heat laps.
- If you run aggressive canyon or track sessions, prioritize the setup with more thermal headroom.
- Wheel clearance should be checked carefully on cars with non-OE wheels or aftermarket brake hardware.
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 uses long-fiber construction, which is stronger than the chopped-fiber CCM used in most OEM carbon-ceramic rotors.
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.
365mm suits steel-brake R8 4S owners wanting a lighter, road-focused upgrade with simpler fitment.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
380mm is the stronger choice for factory-ceramic cars or drivers who want more heat capacity for repeated hard use.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
For the hardest circuit use, choose the largest compatible setup with confirmed caliper and wheel clearance.

FAQ
Will a StopFlex carbon ceramic brake kit for my Audi R8 4S fit the factory calipers, or do I need different calipers?
That depends on whether your R8 4S started with the 365mm steel package or the 380mm factory ceramic setup. On this chassis, caliper and rotor sizing must match exactly, so factory-caliper compatibility should be confirmed before ordering.
Which StopFlex carbon ceramic size is correct for my Audi R8 4S Coupe or Spyder: 365mm or 380mm?
Use 365mm if your car is the steel-brake R8 configuration, and 380mm if it was built around the factory ceramic size. If the car has already been modified, verify the current caliper, hat, and wheel clearance instead of ordering by model year alone.
Is a StopFlex carbon ceramic brake kit a good choice for daily street use on an Audi R8 4S, including cold first stops?
For most R8 4S street cars, yes, if you want less rotating mass and cleaner day-to-day use. The key buying question is whether you want factory-like street manners first, because cold bite and pedal feel should be chosen with daily use in mind.
Do I need extra cooling or a bigger setup if I’m upgrading my Audi R8 4S to a StopFlex carbon ceramic kit for repeated hard driving?
If your R8 4S sees long mountain runs, heavy-speed stops, or track days, the larger setup is the safer choice for heat margin. Dedicated cooling is usually more relevant once sessions get long or the car is run repeatedly at high speed, especially on Spyder or heavier street-trim cars.
