Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2003-2009 Mercedes-Benz E-Class / AMG (W211/S211). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2003-2009 | OEM AMG 6-Piston Caliper / 390mm | OEM AMG 4-Piston Caliper / 380mm | 20" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 390 mm rotor sets the minimum wheel size at 20" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front caliper is the OEM AMG 6-Piston Caliper matched to the 390mm carbon-ceramic front rotor. Six pistons spread clamping load evenly across a larger pad, which keeps pedal feel consistent as the discs heat during repeated hard stops.
Rear Caliper
The rear runs the OEM AMG 4-Piston Caliper on a 380mm carbon-ceramic disc, adding rear thermal capacity so the front axle isn't doing all the work on long descents or track sessions. It works with the W211's cable parking brake, no EPB actuator conversion needed.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.
Get Your Fitment Confirmed
Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
Will these hold up in winter and cold starts better than my worn factory rotors?
Cold carbon-ceramic physics are real: an untuned CCB disc bites a little less than cold iron before it's up to temperature. StopFlex tunes both the pad compound and the disc's ceramic coating for cold starts, so first-stop feel on a cold W211 comes very close to summer feel. Leave a bit of extra following distance on your first stops on the coldest mornings; after that the system is at temperature and feel is normal.
My E-Class keeps warping its factory rotors. Does carbon ceramic actually fix that?
The recurring warping and short rotor life on the OEM W211 setup comes from iron discs distorting under heat cycling. Carbon-ceramic discs handle heat far better and resist the thermal distortion that causes the pulsing pedal, so you stop replacing warped rotors every year or two. The pads are a low-metallic resin composite with steel, copper, and aramid fiber, roughly 0.44 friction coefficient, stable to about 750 °C.
I have an E63; will this fit my exact car, or is it a generic W211 kit?
Every kit is built for your confirmed trim. The AMG V8 cars can use different front knuckles, hub geometry, and wheel clearance than the six-cylinder E280/E320/E350 cars sharing the W211 chassis, so we cut the brackets and set the rotor-hat offsets to your specific car. We do not make a platform-wide bolt-on claim; you confirm the trim first, then we match it.
What wheels do I need to run the 390mm front rotor?
The 390mm front disc requires a minimum 20-inch wheel. Wheels under 20 inches will not clear the rotor, and spoke geometry matters too, not just diameter. Send your wheel details during fitment and we'll confirm clearance with the AMG 6-piston front caliper before anything ships.
