Mercedes-Benz AMG G65 / G63 / G55 (W463) Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2006-2018 Mercedes-Benz AMG G65 / G63 / G55 (W463) Carbon Ceramic Brake Kits
The W463 AMG G55, G63, and G65 are heavy, tall, high-power G-Wagens that put unusual thermal load into the brakes for a street SUV. Buyers usually want stronger repeat-stop confidence, lower rotor wear sensitivity, and a cleaner premium solution than frequent iron-brake replacement.
- Body style: SUV
- Front rotor reference: G65/G63: 390mm; G55: 350mm
- Rear rotor reference: G65/G63: 345mm; G55: 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.
Use the stock-size matched kit for the cleanest fit and the most sensible daily-driven upgrade on a W463.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
For hard canyon, mountain, or repeated high-speed stops, choose the larger matched setup your G55 or G63/G65 can properly support.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
For the most aggressive use, only choose the biggest compatible package after confirming caliper, wheel, and heat-management margin.

FAQ
Can I upgrade my Mercedes-Benz AMG G65 / G63 / G55 (W463) to a StopFlex carbon ceramic brake kit with the factory calipers, or do I need aftermarket calipers?
That depends on which W463 brake package your truck has and which StopFlex kit you are selecting. Some buyers keep the factory AMG calipers, while others move to a matched caliper-and-rotor setup for larger-size conversions, so fitment should be confirmed before ordering.
Which StopFlex carbon ceramic size is correct for my W463: the G55 350/330 setup or the G63/G65 390/345 setup?
Match the kit to the original brake configuration of your exact vehicle. G55 models in this row use the smaller 350mm front and 330mm rear sizing, while G63 and G65 use 390mm front and 345mm rear, so ordering by model alone can cause confusion.
Is a StopFlex carbon ceramic brake kit a good daily-use upgrade for a W463, including cold first stops and normal street driving?
Yes, if you want a premium street-biased upgrade and your priority is cleaner operation with more stable repeat-stop feel on a very heavy SUV. For a daily W463, it is worth confirming the pad and system tuning so the first cold stop feels appropriate for normal road use.
Will a StopFlex carbon ceramic brake kit on a W463 handle prolonged hard use, mountain descents, or repeated fast stops, and do I need extra cooling?
This platform's mass means heat management matters more than on lighter AMG models, so carbon ceramic can be especially useful when the truck is driven hard. For repeated downhill or aggressive road use, correct sizing, wheel airflow, and overall setup matter more than adding cooling parts by default.
