2013-2018 Mercedes-AMG A45 (W176) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2013-2018 Mercedes-AMG A45 (W176) Carbon Ceramic Brake Kit — OEM-Size Replacement
The W176 Mercedes-AMG A45 is a heavy-braking 4MATIC hot hatch, and repeated mountain or track use can push the OEM 350mm front and 330mm rear iron rotors into heat checking, dust, and pedal fade. This StopFlex OEM-size carbon-ceramic kit keeps the factory brake geometry while replacing the rotors, pads, hats, and floating hardware with a lower-dust, lower-unsprung-mass package built around the A45 rotor references. It is for the listed 2013-2018 A45 W176 brake setup only, so rotor size and trim confirmation matter before ordering.
- Built around the A45 W176 OEM-size rotor references: 350mm front and 330mm rear, not a big-brake conversion that changes caliper placement.
- Carbon-ceramic friction rings reduce rotating unsprung mass versus comparable iron discs, which matters on the front-heavy 4MATIC A45 during turn-in and curb strikes.
- The kit includes matched pads, aluminum hats, and floating hardware so the 350mm front and 330mm rear carbon-ceramic rotors can expand under track heat without being rigidly locked to the hat.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG A45 (W176) |
| Model years | 2013-2018 |
| Front rotor reference | A45: 350mm |
| Rear rotor reference | A45: 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 2013-2018 Mercedes-AMG A45 W176?
No. This page is limited to W176 A45 cars that use the listed OEM-size brake references: 350mm front rotors and 330mm rear rotors. Confirm your VIN, existing rotor diameters, and caliper package before ordering.
Do I need different calipers or brake lines?
This is an OEM-size replacement kit, so it is designed around the factory A45 caliper locations for the 350mm front and 330mm rear setup. It is not a larger-diameter big-brake kit and should not require caliper relocation when the car matches the listed brake configuration.
Will the electronic parking brake and auto-hold still work?
The kit replaces the rear rotor, pad, hat, and floating hardware while retaining the vehicle’s factory rear brake architecture. If your W176 A45 is equipped with the factory electronic parking brake, confirm the rear hardware configuration during order review so EPB function is preserved.
Why choose carbon-ceramic instead of another iron rotor set for the A45?
Iron replacement discs are lower cost, but the A45’s 350mm front brakes see high thermal load during repeated hard stops. Carbon-ceramic rotors offer better heat stability, much lower brake dust, corrosion resistance, and reduced rotating mass for owners who drive hard or want cleaner open-spoke wheels.
