2008-2015 Mercedes-Benz C180 / C200 / C250 / C300 / C350 / C63 (W204/S204/C204) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
W204/S204/C204 C-Class owners shop this kit when repeated heat cycles, iron-rotor dust, and front brake fade become the limit on fast road or track use. StopFlex pairs 360 mm front carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-piston front caliper options and 330 mm rear carbon-ceramic rotors with Brembo V4 / GT4 / GTS4 4-piston rear options. Each kit is built around the confirmed C180, C200, C250, C300, C350, or C63 trim, so hat offsets and brackets are matched to the exact W204/S204/C204 geometry rather than assumed from the chassis name.
- 360 mm is the largest rotor in this W204/S204/C204 package, so 19 inch wheels are the minimum; spoke shape and wheel offset still need a clearance check.
- Front choices are V6, GT6, or GTS6 6-piston Brembo calipers, all matched to 360 mm StopFlex carbon-ceramic front rotors for this C-Class application.
- Rear choices are V4, GT4, or GTS4 4-piston Brembo calipers, all matched to 330 mm StopFlex carbon-ceramic rear rotors to keep rear brake contribution engineered with the front upgrade.

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 360 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, with each option paired to a 360 mm carbon-ceramic rotor for this W204/S204/C204 kit. The V6 option is a Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, the GT6 option is a Genuine Brembo GT | M6 6-Piston Caliper, and the GTS6 option is a Genuine Brembo GT | S6 6-Piston Caliper. The 6-piston layout distributes pad pressure across a larger swept area than the factory-style single-caliper setup, improving clamp consistency and pedal confidence under repeated high-speed stops.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 330 mm carbon-ceramic rotors, chosen to support rear brake stability instead of leaving the rear axle as an afterthought. The V4 is a Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, the GT4 is a Genuine Brembo GT | M4 4-Piston Caliper, and the GTS4 is a Genuine Brembo GT | S4 4-Piston Caliper.
Front & rear, engineered together: The 360 mm front and 330 mm rear carbon-ceramic package is engineered as one brake system, so piston selection, rotor diameter, pad choice, and hydraulic behavior are considered together. That matters on the C63 as much as the C180-C350 because front-only brake changes can alter bias, rear contribution, and ABS behavior if the rear axle is not matched correctly.
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.

FAQ
Will this kit fit my exact C180, C200, C250, C300, C350, or C63?
StopFlex does not treat W204, S204, C204, and C63 fitment as one shared bolt-on pattern. Before production, your exact model year, body style, trim, hub data, and wheel setup are confirmed so the caliper brackets and rotor-hat offsets are built for that car.
What wheel size do I need for the 360 mm front rotor?
This kit requires at least 19 inch wheels because the front rotor is 360 mm. Wheel diameter alone is not enough; spoke profile, inner barrel shape, offset, and spacer use must be checked against the selected Brembo V6, GT6, or GTS6 front caliper.
Will the parking brake still work?
Yes, the W204/S204/C204 does not use a factory electronic parking brake. The car uses a foot-operated mechanical parking brake, so rear fitment is engineered around retaining the mechanical parking-brake function where applicable.
Why choose carbon-ceramic rotors instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass compared with iron rotors while improving heat stability during repeated hard stops. On this kit, the 360 mm front and 330 mm rear rotor package is paired with genuine Brembo 6-piston and 4-piston caliper options instead of mixing unrelated front and rear hardware.
