2000-2006 Mercedes-Benz S430 / S500 / S600 / S55 / S65 (W220) CCB Big Brake Kit — Genuine Alcon RC6 6-Piston Caliper Front + Genuine Alcon RC4 4-Piston Caliper Rear Setup
The W220 S-Class is a heavy sedan, and S55/S65 AMG torque makes factory iron brakes work hard on repeated highway stops, mountain descents and track-style driving. This StopFlex kit uses 380mm carbon-ceramic rotors with a Genuine Alcon RC6 6-Piston Caliper front setup and Genuine Alcon RC4 4-Piston Caliper rear setup to add heat capacity, reduce brake dust and cut rotating mass versus comparable iron hardware. Each kit is engineered against the buyer’s exact S430, S500, S600, S55 or S65 trim, because W220 knuckle, hub and wheel-clearance details cannot be assumed from the chassis code alone.
- 380mm front and rear carbon-ceramic rotors require 19-inch or larger wheels on the W220; wheels under 19 inches will not clear the package, and spoke clearance must still be checked.
- The front axle uses the Genuine Alcon RC6 6-Piston Caliper, giving this heavy S-Class a larger, stiffer front brake package for repeated high-energy stops.
- Brackets, rotor-hat offsets and caliper mounting are engineered for the confirmed S430, S500, S600, S55 or S65 trim rather than sold as a one-size W220 fitment.

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.
| Wheel Size (Standard) | Disc Range |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |

| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |
Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses the exact Genuine Alcon RC6 6-Piston Caliper specified for this W220 kit. Six pistons spread pad pressure across the carbon-ceramic rotor face for consistent clamping and a firmer pedal response under repeated stops. Alcon is a recognized performance brake manufacturer, and this genuine caliper gives the front axle a rigid, motorsport-derived foundation without relying on an unbranded casting.
Rear Caliper (Balance)
The rear axle uses the Genuine Alcon RC4 4-Piston Caliper with a 380mm carbon-ceramic rotor to keep rear torque contribution matched to the front upgrade. Because the W220 uses a foot-operated mechanical parking brake rather than an electronic parking brake caliper, EPB integration is not required for this kit.
Front & rear, engineered together: The RC6 front and RC4 rear package is engineered as a matched system so front brake torque, rear contribution, rotor diameter and pad compound work together. That matters on a W220 because adding only a large front kit can change pedal feel and brake balance on a long-wheelbase, heavy S-Class platform.
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 380mm kit fit my exact W220 trim?
Fitment is confirmed per exact S430, S500, S600, S55 or S65 trim before production. StopFlex does not assume every W220 shares the same bracket geometry, rotor-hat offset or caliper clearance, especially between standard models and AMG variants.
What wheel size do I need for the 380mm rotors?
This kit requires 19-inch or larger wheels because the largest rotor is 380mm. Wheel diameter alone is not enough; spoke shape, offset and barrel profile must also clear the Genuine Alcon RC6 front caliper and RC4 rear caliper.
Does this W220 kit need EPB-compatible rear calipers?
No. The 2000-2006 W220 S-Class uses a foot-operated mechanical parking brake system, so there is no factory electronic parking brake motor to retain on the rear caliper.
Why choose carbon-ceramic instead of another iron brake kit?
Carbon-ceramic rotors reduce brake dust, resist heat-related fade and lower rotating mass compared with a similar-size iron rotor package. On a heavy W220 S-Class, those benefits are most noticeable during repeated high-speed braking and on open-wheel cars where iron dust is visible.
