Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2006-2008 Mercedes-AMG R63 (W251). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| R63 | 390mm | 365mm | 20" |
Keep Your Factory Calipers?
Yes — if your front factory calipers are fixed 4-piston or more. The rear axle has no restriction. Cars with 1- or 2-piston floating front calipers should use the Full Upgrade kit (calipers + discs) instead. Discs are built to the factory rotor specs shown above; if you run aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood), we simply confirm the caliper model, pad shape, and rotor dimensions before production.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
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.
Winter & Cold-Weather Braking
Winter question, straight answer: untuned ceramic discs bite less when cold. StopFlex optimized the pad compound and the rotor's ceramic coating for cold operation, so cold-start braking in winter feels very close to warm-weather braking. Extra following distance on freezing first stops is still smart; severe-winter daily cars should run 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
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.

Send the exact vehicle details, current rotor sizes, and caliper type before ordering. Every StopFlex order is confirmed against your VIN-level configuration before production.
FAQ
Does this fit my exact R63 (W251), and will it work with the factory calipers?
This kit is built for the 2006-2008 R63 AMG (W251) running the factory 390mm front and 365mm rear rotor sizes. It's a direct replacement: the carbon-ceramic discs, hats, pads, and floating hardware bolt to your existing AMG calipers, which on the R63 are a multi-piston fixed design up front. Because it reuses the front calipers, this only applies to cars whose front calipers are 4-piston or more, which the R63 satisfies. Confirm your rotor diameters before ordering, since we match the exact factory sizes.
How do these behave in winter on a cold car?
Physics first: an untuned cold carbon-ceramic disc bites less than cold iron on the very first stops. That's normal for the material, not a defect. We addressed it two ways for the R63 setup — the low-metallic resin-composite pad compound and the disc's ceramic coating are both optimized for cold starts, so cold-car feel now comes very close to summer feel. On the coldest first stops of the day, leave a little extra following distance until everything is up to temperature. After that first mile the R63 stops the way you expect from a 5,000+ lb AMG.
Why replace with carbon ceramic instead of going back to iron rotors?
The R63's original setup was carbon ceramic from the factory, and matching that keeps the car's weight distribution and pedal character correct. Each carbon-ceramic disc cuts significant unsprung and rotating mass off the corners of a heavy W251, which helps steering response and ride over the iron alternative. The rotors also resist warping and fade far better under repeated hard stops from this car's 6.2L V8 pace, and they shed the heavy brake dust that coats wheels on iron pads.
What does the kit include, and what will I still need?
You get the carbon-ceramic front (390mm) and rear (365mm) discs, the mounting hats, the floating hardware that connects disc to hat, and a full set of carbon-ceramic-specific pads. The pad compound runs an average friction coefficient around 0.44 and holds up to roughly 750 °C with strong anti-fade behavior. You reuse your existing AMG calipers and caliper brackets. Plan on standard consumables like brake fluid and a proper bed-in on install.
