2005-2010 Mercedes-Benz CLS350 / CLS500 / CLS550 / CLS55 / CLS63 (C219) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
The C219 CLS is heavy enough to punish factory iron brakes during repeated high-speed stops, and AMG trims add more front-end load and wheel-clearance sensitivity. This StopFlex kit pairs 380mm carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-Piston Caliper Options up front and Brembo V4 / GT4 / GTS4 4-Piston Caliper Options at the rear for more heat capacity, lower brake dust, and reduced rotating mass versus iron. Each kit is built to the confirmed CLS350, CLS500, CLS550, CLS55, or CLS63 trim so the brackets, rotor hats, and caliper position match the exact car rather than a generic C219 assumption.
- 380mm front and rear carbon-ceramic rotors require 19-inch or larger wheels; spoke clearance must be checked against the selected Brembo caliper profile.
- Front choices are V6, GT6, or GTS6 6-piston Brembo calipers, each matched to a 380mm rotor for the C219 front axle.
- CLS55 and CLS63 AMG fitment is verified separately from CLS350, CLS500, and CLS550 because knuckle, hub, offset, and wheel-clearance differences can change bracket and hat requirements.

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.

| 19" | 355 mm – 380 mm |

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, giving the C219 a larger multi-piston clamping package for firmer pedal response and more even pad loading across the 380mm rotor. The buyer chooses V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, GT6 = Genuine Brembo GT | M6 6-Piston Caliper, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper, all paired with a 380mm front carbon-ceramic rotor. These are genuine Brembo caliper families, selected for proven stiffness, serviceability, and compatibility with StopFlex trim-specific mounting hardware.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with 380mm carbon-ceramic rotors to keep rear torque contribution matched to the upgraded front axle. The C219 uses a foot-operated mechanical parking brake system, so there is no factory EPB actuator to integrate into the rear caliper package.
Front & rear, engineered together: StopFlex engineers the 6-piston front and 4-piston rear package as one brake system so piston area, rotor diameter, pad selection, and hydraulic behavior are matched to the exact CLS trim. That avoids the front-only upgrade problem where added front torque can make the car nose-heavy under braking and reduce rear stability on repeated hard stops.
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 CLS350, CLS500, CLS550, CLS55, or CLS63?
Yes, only after StopFlex confirms your exact year, trim, hub/knuckle configuration, and wheel data. The C219 name alone is not used for fitment because AMG and non-AMG cars can require different brackets, rotor-hat offsets, and caliper positioning.
What wheel size is required for the 380mm carbon-ceramic rotors?
A 19-inch wheel is the minimum because this kit uses 380mm rotors front and rear. Barrel clearance and spoke clearance still have to be checked against the selected Brembo V6, GT6, GTS6, V4, GT4, or GTS4 calipers.
Will the parking brake still work on a C219 CLS?
Yes, the C219 CLS uses a mechanical foot-operated parking brake rather than an EPB motor on the rear caliper. The rear package is engineered around that mechanical parking-brake layout.
Why switch a C219 CLS from iron rotors to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, cut rotating mass, and handle repeated high-temperature stops better than conventional iron. On a heavy CLS500, CLS550, CLS55, or CLS63, that helps preserve pedal consistency and reduces the heat load that causes fade and rotor wear.
