Audi RSQ8 / SQ8 / Q8 (4M) Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2019-2026 Audi RSQ8 / SQ8 / Q8 (4M) Carbon Ceramic Brake Kits
The Audi Q8 4M range spans luxury cruiser to very fast RSQ8, but all variants carry substantial mass and ask a lot from front brakes under repeated hard stops. On this platform, buyers usually care most about matching the kit to the exact factory rotor/caliper package, wheel clearance, and whether the SUV is street-only or driven hard in mountain or high-speed use.
- Body style: SUV
- Front rotor reference: RSQ8: 420mm, 440mm(CCB); SQ8: 400mm; Q8: 350mm, 375mm
- Rear rotor reference: RSQ8: 370mm; SQ8: 350mm; Q8: 350mm
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.
Choose the size that matches your factory brake package for the cleanest street upgrade with the fewest fitment surprises.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
For fast-road or occasional track use, move toward the largest package your calipers, hats, and wheel barrel clearance are engineered to support.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
For sustained heavy lapping or repeated high-speed stops, use the maximum correctly matched setup with proven cooling around the 4M chassis.

FAQ
Can I upgrade my Audi RSQ8, SQ8, or Q8 (4M) to a StopFlex carbon ceramic brake kit while keeping the factory calipers?
Sometimes yes, but only when the StopFlex kit is built around your exact factory caliper and rotor dimensions. On the 4M platform, Q8, SQ8, and RSQ8 front packages differ enough that you should verify caliper compatibility before ordering.
Which StopFlex carbon ceramic size should I choose for my Audi Q8 4M: Q8, SQ8, or RSQ8 setup?
Match the kit to the exact stock brake package on the vehicle unless you are also changing calipers and confirming wheel clearance. The common confusion points on this chassis are Q8 375mm vs SQ8 400mm fronts and RSQ8-specific larger packages.
Is a StopFlex carbon ceramic brake kit a good daily-use upgrade for my Audi Q8 4M, especially for cold first stops?
Yes, if your priority is a cleaner and lighter street setup and you choose a street-friendly pad and matched kit. Daily drivers usually care more about predictable cold behavior and quiet operation than maximum heat capacity.
Will a StopFlex carbon ceramic brake kit solve heat issues on my Audi RSQ8, SQ8, or Q8 4M during repeated hard use, or do I still need cooling?
It helps, but this is still a heavy, fast SUV, so cooling and airflow remain important for prolonged abuse. If you do mountain descents, towing, or repeated high-speed stops, treat ducting and airflow as part of the package decision.
