2014-2019 Mercedes-AMG CLA45 (C117/X117) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2014-2019 Mercedes-AMG CLA45 (C117/X117) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2014-2019 Mercedes-AMG CLA45 C117/X117 uses a compact AMG brake package with 350mm front rotors and 330mm rear rotors, so repeated hard stops put a lot of heat into a relatively small rotor envelope. This StopFlex OEM-size carbon-ceramic kit replaces the iron discs with carbon-ceramic rotors, matched pads, hats, and floating hardware to reduce brake dust and rotating mass while keeping the original caliper locations and rotor diameters. It is built for CLA45 owners who want stronger heat control and cleaner open-wheel appearance without changing to a big-brake conversion.
- OEM-size replacement for the CLA45 brake package: 350mm front rotors and 330mm rear rotors.
- Designed around the C117 coupe and X117 Shooting Brake AMG CLA45 fitment, not the CLA250 or non-AMG CLA brake package.
- Carbon-ceramic rotors reduce the unsprung and rotating mass at all four corners compared with same-size iron discs, improving steering response and wheel control on this nose-heavy 4MATIC chassis.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG CLA45 (C117/X117) |
| Model years | 2014-2019 |
| Front rotor reference | CLA45: 350mm |
| Rear rotor reference | CLA45: 330mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 18" (for the 350 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 350 mm rotor, so the minimum wheel size is 18". Wheels under 18" 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 2014-2019 CLA45 AMG?
This page is limited to 2014-2019 Mercedes-AMG CLA45 C117/X117 cars with the listed 350mm front and 330mm rear brake setup. Before ordering, confirm your rotor diameters, caliper package, model year, and wheel clearance because CLA250 and non-AMG CLA parts are not interchangeable.
Does the kit keep the factory parking brake and rear brake functions?
Yes, the kit is an OEM-size rotor replacement for the CLA45 rear brake layout, so it is intended to work with the factory rear calipers and electronic parking brake system when installed on the correct 330mm rear setup.
Why switch from the factory iron rotors on a CLA45?
The factory-size iron discs can build heat quickly during repeated mountain-road or track-session braking. Carbon-ceramic rotors handle sustained heat with less fade, create much less visible dust on AMG wheels, and remove rotating mass without changing the 350mm/330mm brake sizing.
Is this a street kit, a track kit, or both?
It is an OEM-size carbon-ceramic replacement kit for street cars that also see aggressive driving or track-day heat. Use the supplied compatible pads, bed the system correctly, and inspect rotor condition after track use because carbon-ceramic service life depends on temperature, pad compound, and cooling.
