Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2017-2023 Mercedes-AMG E63S / E63 / E53 / E43 (W213/S213/C238/A238). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| E63S/E63 | 390mm, 402mm (CCB) | 21" | |
| E53 | 370mm | 19" | |
| E43 | 360mm | 19" | |
| E63S/E63/E53/E43 | 360mm | 19" |
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
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.
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.
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.
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
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 E63S, E63, E53, or E43 without changing the calipers?
Yes, this is a direct replacement that reuses your factory AMG calipers. It fits front rotor sizes of 390mm or 402mm (CCB) on E63S/E63, 370mm on E53, and 360mm on E43, with 360mm rears across all four trims. Confirm which front rotor diameter your car actually runs, since E63/E63S left the factory in more than one size. Direct replacement requires a 4-piston or larger front caliper, which the E63 and E63S carry; verify E53 and E43 front caliper piston count before ordering.
How do these behave in winter and on cold morning stops?
A cold carbon-ceramic disc naturally bites a little less than cold iron on the first stop, since ceramic needs some heat to reach full friction. That is physics, not a fault. StopFlex tuned both the low-metallic resin-composite pad and the disc's ceramic coating for cold starts, so cold-car feel on your E-Class now lands very close to warm summer feel. On the coldest first stops, leave a little extra following distance until the front rotors take heat.
If my E63S already has factory carbon ceramic brakes, why not just buy OEM replacements?
Factory CCB replacement on a W213 E63S can run near five figures per axle at a dealer, which is the exact liability that scares off used-car buyers. This kit gives you carbon-ceramic rotors, pads, hats, and floating hardware that bolt to your existing 390mm or 402mm front calipers, so you keep the CCB weight savings and fade resistance without the OEM part number and its price. E-Class owners who never had B07 can move to carbon-ceramic while retaining their steel-caliper hardware, provided the front caliper is 4-piston or more.
Will these clear my wheels and work with the electronic parking brake?
These match the factory rotor diameters for your trim, so wheels that cleared your OEM front rotor will clear these front discs. The 360mm rear applies to all four trims and integrates with the W213 electronic parking brake through the reused factory caliper. Since you are keeping your own calipers and matching factory diameters, EPB function is retained. If you run aftermarket wheels or spacers, send your setup for a clearance check before ordering.
