Mercedes-Benz AMG SL65 / SL63 (R231) Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2013-2020 Mercedes-Benz AMG SL65 / SL63 (R231) Carbon Ceramic Brake Kits
The R231 SL63 and SL65 are heavy, very fast AMG roadsters that mix autobahn pace with grand-touring use. Buyers usually want sharper brake response and lower unsprung weight without giving up refined street manners.
- Body style: Roadster
- Front rotor reference: SL65/SL63: 390mm, 402mm(CCB)
- Rear rotor reference: SL65/SL63: 360mm
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.
390mm front is the safer match for stock-style street-driven SL63/SL65 cars that want a straightforward upgrade path.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
402mm front suits owners targeting the factory CCB-size envelope and more thermal margin for repeated hard stops.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
For the hardest use, choose the largest compatible setup with confirmed wheel and caliper clearance before ordering.

FAQ
Will a StopFlex carbon ceramic brake kit for the Mercedes-Benz AMG SL65 / SL63 (R231) fit my factory AMG calipers, or is it only for aftermarket calipers?
That depends on which front setup your R231 has now, because this row spans both 390mm and 402mm-front configurations. Order only against your exact caliper and disc dimensions, and verify bracket, hat, and pad shape compatibility before buying.
Which StopFlex carbon ceramic brake size should I choose for my Mercedes-Benz AMG SL65 / SL63 (R231): 390mm or 402mm front?
Use 390mm if your car is based on the standard AMG iron-brake size and you want the simplest stock-style fitment. Choose 402mm only if your car matches the larger factory carbon-ceramic-size layout or you are converting with confirmed caliper and wheel clearance.
Is a StopFlex carbon ceramic brake kit on the Mercedes-Benz AMG SL65 / SL63 (R231) still a good choice for street driving, cold first stops, and daily use?
Yes, if your priority is a lighter, cleaner-feeling brake package rather than a track-only setup. Most R231 buyers should still ask for a street-biased pad and confirm expected cold-stop behavior before ordering.
Does the Mercedes-Benz AMG SL65 / SL63 (R231) need extra brake cooling with a StopFlex carbon ceramic brake kit for mountain driving or repeated hard use?
For fast road use, the kit should mainly be sized correctly and paired with the right pad compound. For repeated heavy stops in a 4,000-plus-pound AMG roadster, cooling airflow and fluid condition become more important, so hard-use cars should plan the full system together.
