Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2005-2010 Mercedes-Benz CLS-Class / AMG (C219). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2005-2010 | OEM AMG 6-Piston Caliper / 390mm | OEM AMG 4-Piston Caliper / 380mm | 20" |
Every StopFlex kit is bespoke-engineered for your exact model and trim — brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, never assumed from the platform. Trims that share a chassis name can differ mechanically: a pure performance variant often carries different knuckles, hub geometry, and wheel ET clearance than the standard models, so parts that bolt onto one are not the parts that fit the other. Calipers, pads, rotor hats, floating hardware, and brake lines ship as one matched system built to your confirmed trim. Modified knuckles, uprights, or non-factory suspension mounting points must be reviewed 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
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.
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.
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
This kit uses the OEM AMG 6-piston fixed front caliper, the same clamping hardware AMG specified for the fast C219 CLS. Six pistons spread pad load evenly across the 390mm carbon-ceramic disc for a consistent, firm pedal.
Rear Caliper
The rear runs the OEM AMG 4-piston caliper on the 380mm rotor, adding rear thermal capacity so the fronts aren't doing all the work on long descents and repeated high-speed stops.
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
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.
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 this kit fit my exact CLS trim, or is it a generic W219 part?
It is built for your confirmed trim, not assumed from the C219 name. The AMG CLS55 and CLS63 can differ from CLS500/550 in front knuckle geometry, hub offset, and wheel clearance, so we match the brackets, rotor-hat offsets, and caliper mounting to your specific car after you confirm year and VIN. We do not make a platform-wide bolt-on claim.
What wheels do I need to clear the 390mm front rotors?
The 390mm front disc requires a minimum 20-inch wheel. Anything under 20 inches will not clear the rotor, and spoke shape matters too, so send us your wheel details and we'll confirm clearance before you buy.
How do these carbon-ceramic brakes behave in winter and cold starts?
A cold, untuned carbon-ceramic disc bites less than cold iron on the first stops. That's physics, not a defect. We've tuned both the pad compound and the disc's ceramic coating for cold operation, so cold-car braking feel now comes very close to warm summer feel. On the coldest first stop or two, leaving a little extra following distance is still smart.
What does the kit include and what are the pads made of?
You get the OEM AMG 6-piston front calipers, AMG 4-piston rears, 390mm front and 380mm rear carbon-ceramic rotors, hats, pads, hardware, and braided lines. The pads are a carbon-ceramic-specific low-metallic resin-composite with steel, copper, and aramid fiber, around 0.44 average friction, with heat resistance to about 750 C and strong anti-fade behavior for a 5.4L or 6.2L AMG CLS.
