2015-2023 Mercedes-Benz C180 / C200 / C300 / C400 / C450 / C43 / C63 / C63 S (W205/S205/C205/A205) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
W205/S205/C205/A205 C-Class owners shop this kit when the factory iron brakes are producing dust, heat fade, rotor wear, or when an AMG owner wants carbon-ceramic performance without dealer-level replacement cost. StopFlex pairs 380 mm carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-piston front caliper options and matching 380 mm rear 4-piston options to add heat capacity while reducing rotating and unsprung mass versus comparable iron hardware. Each kit is built around the confirmed C180, C200, C300, C400, C450, C43, C63, or C63 S configuration so brackets, rotor-hat offsets, lines, and caliper mounting match the specific car, not just the W205 chassis name.
- 380 mm front and 380 mm rear carbon-ceramic rotors make 19 inch wheels the minimum; wheels under 19 inches will not clear the package, and spoke clearance still must be checked.
- Front choices are V6, GT6, or GTS6 6-piston Brembo calipers on 380 mm rotors, matched to the buyer's C-Class trim rather than assumed from the W205/S205/C205/A205 platform.
- C180/C200/C300/C400/C450 and AMG C43/C63/C63 S variants can differ in uprights, hub offsets, and wheel ET, so StopFlex engineers the brackets and hats for the exact trim confirmed at order time.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 380 mm front 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.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses Brembo V6 / GT6 / GTS6 6-Piston Caliper Options to increase pad area control and clamp consistency over the 380 mm carbon-ceramic rotor. The buyer selects V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper — 380 mm rotor, GT6 = Genuine Brembo GT | M6 6-Piston Caliper — 380 mm rotor, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper — 380 mm rotor. Each option is a genuine Brembo aluminum fixed caliper package selected for credible OEM-performance or Brembo GT-series hardware, not a generic cast-look replacement.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 380 mm carbon-ceramic rotors to keep rear torque, thermal capacity, and chassis stability matched to the front upgrade. EPB integration is handled according to the confirmed W205/S205/C205/A205 trim and rear hardware package so the factory electronic parking brake function is addressed during engineering.
Front & rear, engineered together: A 380 mm front-only conversion can move brake torque and heat capacity forward without correcting the rear axle, especially on heavier C43/C63/C63 S use cases. This full kit lets StopFlex set front and rear rotor dimensions, caliper mounting, pad selection, hats, and lines together so pedal feel and brake balance are engineered as one system.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

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.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact C180, C300, C43, C63, or C63 S?
Fitment is confirmed per vehicle before production. W205/S205/C205/A205 trims can use different uprights, hubs, brake packages, and wheel offsets, so StopFlex builds the brackets, rotor-hat offsets, lines, and caliper mounting for your exact model and trim rather than selling one platform-wide bracket set.
What wheel size do I need for the 380 mm setup?
The 380 mm front and rear rotors require 19 inch or larger wheels. Wheel diameter is only the first check; spoke shape, barrel profile, offset, and spacer use must also be verified against the Brembo 6-piston front caliper and rear 4-piston caliper package.
Will the electronic parking brake still work?
The W205-generation C-Class uses an electric parking brake, so rear fitment must address EPB function. StopFlex confirms the rear configuration for the specific C-Class trim and supplies the rear hardware path needed for the chosen V4, GT4, or GTS4 4-piston rear setup.
Why choose carbon-ceramic instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass while adding heat stability for repeated high-speed stops. On a W205 C43, C63, or C63 S that sees fast street driving or track use, the payoff is cleaner wheels, lower unsprung weight, and more consistent braking temperature control than a comparable iron rotor package.
