2021-2026+ Mercedes-Benz S500 / S580 / S63 (W223/V223) CCB Big Brake Kit — Genuine OEM AMG 6-Piston Caliper Front + Genuine OEM AMG EPB Single-Piston Caliper Rear Setup
The W223/V223 S500, S580 and S63 are heavy, fast luxury sedans, so repeated high-speed braking can expose the limits of iron rotor heat capacity, dust output and rotating mass. This StopFlex kit pairs a Genuine OEM AMG 6-Piston Caliper front setup with 400/420 mm carbon-ceramic front rotors and a 380 mm EPB-compatible rear package to increase thermal margin, reduce brake dust and preserve factory-style electronic parking-brake function. Each kit is built to the confirmed S500, S580 or S63 trim, because knuckle, hub, hat offset and wheel-clearance details can differ inside the same W223/V223 family.
- Front braking is based on the Genuine OEM AMG 6-Piston Caliper with a 400/420 mm carbon-ceramic rotor, sized for the mass and speed of the W223/V223 S-Class platform.
- Rear braking uses a Genuine OEM AMG EPB Single-Piston Caliper with a 380 mm carbon-ceramic rotor, keeping rear brake torque and parking-brake integration part of the engineered package.
- The largest rotor in this kit is 400 mm, so wheels under 20 inches will not clear it; final approval also checks spoke clearance against the AMG 6-piston caliper.

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 400 mm front rotor, so the minimum wheel size is 20". Wheels under 20" 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 upgrade uses the exact Genuine OEM AMG 6-Piston Caliper, giving the W223/V223 S-Class a multi-piston fixed-caliper layout that spreads clamping load across the pad for more consistent pedal response than a small sliding-caliper setup. Its OEM AMG provenance matters on an S500, S580 or S63 because the caliper architecture is derived from Mercedes-AMG brake hardware rather than an unverified universal casting. StopFlex matches this caliper to the confirmed trim’s rotor hat offset, mounting bracket and wheel package instead of treating every W223/V223 as mechanically identical.
Rear Caliper (Balance)
The rear uses the Genuine OEM AMG EPB Single-Piston Caliper with a 380 mm carbon-ceramic rotor to keep rear brake contribution stable without over-biasing the car. Because the W223/V223 S-Class uses an electronic parking brake, this rear package is specified to retain EPB operation when ordered for the correct trim configuration.
Front & rear, engineered together: The 6-piston front and EPB rear assemblies are engineered together so front torque, rear torque, rotor diameter and pad compound work as one brake system. On a heavy S-Class, that matters more than a front-only conversion because poor rear matching can change pedal travel, ABS behavior and braking stability.
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 S500, S580 or S63?
Fitment is confirmed per vehicle, not by chassis name alone. StopFlex verifies the exact W223/V223 trim, brake package, hub geometry, wheel size and spoke clearance before building the brackets, rotor hats and caliper mounting hardware.
What wheel size do I need for the 400/420 mm front setup?
The minimum wheel diameter is 20 inches because the largest rotor in this package is 400 mm. Wheel diameter alone is not enough; the AMG 6-piston caliper also needs spoke clearance, so wheel model and offset must be checked before production.
Will the electronic parking brake and Auto Hold behavior still work?
The rear package uses the Genuine OEM AMG EPB Single-Piston Caliper, so the kit is designed around the factory electronic parking-brake architecture used on the W223/V223 S-Class. Final compatibility is still tied to the confirmed trim and rear brake configuration.
Why switch this S-Class to carbon-ceramic instead of replacing iron rotors?
Carbon-ceramic rotors reduce brake dust, cut rotating and unsprung mass, and hold up better under repeated high-energy stops than conventional iron rotors. For an S500, S580 or S63 with large wheels and frequent high-speed use, the payoff is cleaner wheels, stronger heat margin and less mass at the corners.
