Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2003-2006 Mercedes-AMG CL65 / CL55 (C215). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| CL65 | 390mm | 348mm | 20" |
| CL55 | 360mm | 330mm | 19" |
Keep Your Factory Calipers?
Keep them if the front calipers are fixed 4-piston or more — the rear axle qualifies regardless. Front 1- or 2-piston floating calipers rule out the disc-only route; choose the Full Upgrade kit instead. Every set is machined to the factory rotor specs listed above, and aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood) only need the caliper model, pad shape, and rotor dimensions confirmed before we build.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

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
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
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
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.

FAQ
Does this fit both the CL65 and CL55, and how do I know which rotors I need?
Yes, this page covers both C215 trims from 2003-2006, but the rotor diameters differ, so the kit is trim-specific. The CL65 runs 390mm front / 348mm rear rotors; the CL55 runs 360mm front / 330mm rear. We build to your exact factory reference, so tell us which trim you have and we ship the matching diameters. Mixing sizes across trims will not fit the factory calipers correctly.
Can I keep my factory AMG calipers?
Yes. This is a direct replacement that reuses your factory calipers, hats, and mounting points. The only requirement is that the front factory calipers are 4-piston or more, which the C215 AMG front setup satisfies. You get carbon-ceramic rotors, matched pads, hats, and floating hardware without swapping calipers or reworking the knuckle. Rear caliper piston count is not a limiting factor.
How do these behave in winter or on a cold first drive?
Honest answer: an untuned cold carbon-ceramic disc bites a little less than cold iron on the very first stops. That's normal physics, not a fault. We tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so cold-car feel on the C215 now comes very close to summer feel. Still, leave a bit of extra following distance on the coldest first couple of stops until the discs come up to temperature.
Why go carbon-ceramic on a car this heavy instead of another set of steel two-piece rotors?
The C215 CL65/CL55 is a heavy twin-turbo grand tourer, and its factory two-piece steel rotors with aluminum hats fade and wear under sustained speed and weight. Carbon-ceramic discs cut a large amount of unsprung and rotating mass, run cooler under repeated hard stops, and shed the brake dust that coats staggered AMG wheels. The low-metallic pad averages about 0.44 friction and resists fade to roughly 750 °C, which suits the car's speed and mass.
