2015-2021 Mercedes-AMG C63 S / C63 / C43 / C450 (W205/S205/C205/A205) Carbon Ceramic Brake Kit — OEM-Size Replacement
W205/S205/C205/A205 AMG C-Class owners usually shop carbon ceramic replacement brakes after the factory iron rotors develop vibration under repeated heat, the wheels stay coated in dark pad dust, or the original AMG carbon-ceramic discs need replacement at dealer pricing. This StopFlex OEM-size kit is configured around the exact brake package on the car: C63 S front 390 mm iron or 402 mm carbon-ceramic reference sizes, C63/C43/C450 360 mm front reference size, and 360 mm or 320 mm rear reference size by trim. Carbon-ceramic rotors reduce rotating mass and keep braking performance more consistent during repeated high-speed stops while the supplied pads, hats, and floating hardware keep the installation matched to the factory caliper layout.
- C63 S fitment is built around the factory large front brake package: 390 mm front replacement for iron-equipped cars or 402 mm front replacement for AMG carbon-ceramic-equipped cars.
- C63, C43, and C450 applications on this page use the 360 mm front rotor reference, with rear sizing split between 360 mm on C63/C63 S and 320 mm on C43/C450.
- The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware so the W205-family brake package is replaced as a system rather than mixing new discs with old friction hardware.

| 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 2015-2021 AMG C-Class?
No. This page is limited to Mercedes-AMG C63 S, C63, C43, and C450 models on the W205/S205/C205/A205 platform, and only with the rotor sizes listed here. Confirm front diameter, rear diameter, body style, and whether the car currently has the AMG carbon-ceramic brake option before ordering.
Does the rear electronic parking brake and auto-hold function stay in place?
Yes, when the kit is ordered for the correct rear brake size. The rear package is configured to work with the factory W205-family rear caliper and parking-brake interface; it does not require converting the car to a separate racing parking brake.
Why replace the stock iron brakes with carbon ceramic on a C63, C43, or C450?
The main reasons are lower brake dust, less rotating mass, and better consistency when the brakes are repeatedly heated. On a C63 or C63 S that sees fast road or track use, carbon ceramic also helps reduce the heat-related vibration and fade complaints common with heavy front-engine AMG cars on iron discs.
What should I verify before placing the order?
Verify the exact trim, chassis code, front rotor diameter, rear rotor diameter, and current brake option. C63 S cars may be 390 mm front or 402 mm front depending on brake package, while C43/C450 cars use the smaller rear reference size listed for this page.
