2012-2020 Mercedes-AMG SLK55 / SLC43 (R172) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2012-2020 Mercedes-AMG SLK55 / SLC43 (R172) Carbon Ceramic Brake Kit — OEM-Size Replacement
The R172 SLK55 and SLC43 use a compact AMG roadster chassis with large OEM-format brakes: 360mm front rotors and 330mm rear rotors on this page. This StopFlex OEM-size carbon-ceramic kit replaces the iron wear package with carbon-ceramic rotors, matched pads, hats, and floating hardware to cut brake dust, reduce rotating mass, and keep the factory caliper and wheel fitment envelope. It is built only for the SLK55/SLC43 brake package listed here, so rotor diameter and trim confirmation matter before ordering.
- Direct OEM-size replacement for R172 AMG applications using 360mm front and 330mm rear rotors.
- Designed around the factory SLK55/SLC43 caliper locations, so no big-brake bracket conversion is required for this page’s listed setup.
- Carbon-ceramic discs reduce the dust and heat sensitivity that owners notice when driving an AMG roadster hard on mountain roads or short track sessions.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG SLK55 / SLC43 (R172) |
| Model years | 2012-2020 |
| Front rotor reference | SLK55/SLC43: 360mm |
| Rear rotor reference | SLK55/SLC43: 330mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 19" (for the 360 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 360 mm rotor, so the minimum wheel size is 19". Wheels under 19" 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 R172 SLK or SLC?
No. This page is limited to 2012-2020 Mercedes-AMG SLK55 / SLC43 R172 cars with the listed 360mm front and 330mm rear rotor package. Do not order it for SLK250, SLK300, SLK350, or cars with different rotor diameters.
Do I need different calipers or brackets?
This is an OEM-size replacement kit for the listed SLK55/SLC43 setup, not a caliper conversion. The rotors, pads, hats, and floating hardware are matched to the factory 360mm front and 330mm rear brake layout.
Will the electronic parking brake still work?
Yes, the kit is intended to retain the R172 rear brake and EPB function when installed on the compatible SLK55/SLC43 brake package. The rear parking-brake service mode should be used during installation just as it is for rear pad service.
What should I confirm before ordering?
Confirm the VIN trim, front rotor diameter of 360mm, rear rotor diameter of 330mm, wheel clearance, and whether the car still has its original AMG brake hardware. If any brake parts have been swapped, measure the rotors before purchase.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
