2016-2023 Mercedes-AMG GLC63S / GLC63 / GLC43 (X253/C253) Carbon Ceramic Brake Kit — OEM-Size Replacement
The X253/C253 AMG GLC uses large factory brakes to control SUV mass and AMG power, but repeated high-speed stops can overheat iron rotors and load open-wheel cars with dust. This OEM-size StopFlex kit replaces the listed factory dimensions only: GLC63S/GLC63 with 390mm front and 360mm rear rotors, or GLC43 with 360mm front and 320mm rear rotors. Carbon-ceramic discs with matched pads, hats, and floating hardware reduce rotating mass, resist heat-related fade, and keep the original caliper architecture for a direct replacement path.
- Built only for 2016-2023 Mercedes-AMG GLC63S, GLC63, and GLC43 SUV/Coupe chassis codes X253 and C253 with the rotor sizes listed on this page.
- GLC63S/GLC63 fitment follows the OEM 390mm front and 360mm rear rotor package; GLC43 fitment follows the OEM 360mm front and 320mm rear rotor package.
- The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware so the disc can expand under heat without converting the car to a different brake system.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG GLC63S / GLC63 / GLC43 (X253/C253) |
| Model years | 2016-2023 |
| Front rotor reference | GLC63S/GLC63: 390mm; GLC43: 360mm |
| Rear rotor reference | GLC63S/GLC63: 360mm; GLC43: 320mm |
| 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 kit fit every 2016-2023 AMG GLC?
No. This page is limited to AMG GLC63S, GLC63, and GLC43 X253/C253 models using the exact OEM-size rotor package listed here. Confirm trim, body style, front rotor diameter, rear rotor diameter, and wheel clearance before ordering.
Does it keep the factory parking brake and daily-driver functions?
The kit is designed as an OEM-size replacement using the original caliper layout, so it is intended to retain the vehicle’s factory brake controls, including parking-brake integration where applicable. Verify your rear brake configuration before purchase.
Why switch my GLC63 or GLC43 from iron rotors to carbon ceramic?
Carbon-ceramic rotors reduce brake dust, resist heat saturation during repeated stops, and remove rotating mass from a heavy AWD AMG SUV/Coupe. On the GLC63S/GLC63, the 390mm front rotor size gives the carbon-ceramic disc a large thermal platform without changing the factory brake envelope.
What should I check before ordering?
Measure or verify the factory rotor sizes: GLC63S/GLC63 should be 390mm front and 360mm rear; GLC43 should be 360mm front and 320mm rear. Also confirm wheel size, spoke clearance, production-year fitment, and whether any previous owner changed the brake package.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
