2023-2026+ Mercedes-AMG C63 S / C43 (W206/S206) Carbon Ceramic Brake Kit — OEM-Size Replacement
The W206/S206 AMG C63 S E Performance and C43 put high thermal load into the front axle, and owners shopping this page are usually trying to cut brake fade, iron dust, and rotor mass without changing the factory caliper layout. This OEM-size StopFlex kit replaces the listed C63 S 390mm front / 370mm rear or C43 370mm front / 360mm rear setup with carbon-ceramic rotors, matched pads, hats, and floating hardware. The result is lower rotating unsprung mass, cleaner open-spoke AMG wheels, and fitment that stays tied to the exact rotor package on the car.
- Built only for W206/S206 Mercedes-AMG C63 S E Performance cars with 390mm front and 370mm rear rotors, or C43 cars with 370mm front and 360mm rear rotors.
- Carbon-ceramic friction rings reduce the rotating mass carried by the AMG front multi-piston calipers, improving steering response and repeated-stop stability compared with like-size iron discs.
- The included rear components are designed around the factory rear brake architecture so the car’s electronic parking brake, auto-hold behavior, and street functions are retained when installed correctly.

| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 390 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 390 mm rotor, so the minimum wheel size is 20". Wheels under 20" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this fit every 2023-2026+ W206 or S206 C63 S and C43?
No. This page is limited to the exact AMG trims and rotor sizes listed: C63 S with 390mm front and 370mm rear rotors, or C43 with 370mm front and 360mm rear rotors. Confirm the rotor diameter on your VIN or current brake package before ordering.
Do I need different wheels or calipers?
The kit is an OEM-size replacement, so it is not intended to require a caliper conversion. Wheel clearance still depends on the actual AMG wheel design, spoke shape, and any spacer setup, so confirm clearance if the car has aftermarket wheels or a non-standard winter wheel package.
Will the electronic parking brake and auto-hold still work?
Yes, the rear setup is built to work with the factory Mercedes-AMG rear brake and EPB architecture. Installation should be done with the rear parking brake placed in service mode and completed with the correct pad bedding procedure.
Why switch from the factory iron brakes on a W206 AMG?
The main reasons are lower rotor mass, less visible brake dust, and more consistent high-temperature performance during repeated hard stops. On a C63 S or C43 that sees mountain driving, HPDE use, or frequent high-speed braking, carbon-ceramic rotors also reduce the heat cycling burden on iron discs.
