Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2007-2014 Mercedes-Benz CL-Class / AMG (C216). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2007-2014 | OEM AMG 6-Piston Caliper / 390mm | OEM AMG 4-Piston Caliper / 380mm | 20" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require 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
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.
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.
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 runs the OEM AMG 6-Piston Caliper clamping a 390mm carbon-ceramic rotor. On a coupe this heavy, six opposed pistons keep pad pressure even across the disc, so pedal feel stays consistent from a cold parking lot to repeated highway stops.
Rear Caliper
The rear uses the OEM AMG 4-Piston Caliper on a 380mm carbon-ceramic rotor, adding real thermal capacity out back so the fronts aren't doing all the work on a 4,600+ lb GT. The rear parking brake function is retained as configured on your car.
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
How does this kit behave in winter and on the first cold stops?
Cold carbon-ceramic material bites a little less than cold iron on the very first stop — that's physics, not a defect. StopFlex tunes both the pad compound and the disc's ceramic coating for cold starts, so on this CL the cold-car feel now comes very close to a warm summer pedal. Leave a bit of extra following distance on the coldest first stops until the discs see some heat, and you're good.
Will this fit my exact CL trim, or is it a generic C216 kit?
Every kit is engineered for your confirmed trim. A CL63 and a CL65 can differ in knuckle geometry, hub offset, and wheel clearance, so we match brackets, rotor-hat offsets, and caliper mounting to your specific car — never a blanket platform bolt-on claim. Confirm your VIN and trim and we build to it.
What wheels do I need to clear these rotors?
The front rotor is 390mm, so the minimum wheel size is 20 inches. Wheels under 20 inches will not clear the caliper and rotor. Spoke geometry matters too, not just diameter — send us your wheel details and we'll verify clearance before you order.
Why go carbon-ceramic on a CL63 or CL65 instead of new steel rotors?
This is a heavy V8/V12 GT, and the carbon-ceramic rotors cut significant unsprung and rotating mass while shedding heat far better under sustained braking. The AMG-optioned ceramic system was originally offered on these cars for exactly that reason — you get less fade, less brake dust, and no warped-rotor shudder that plagues the factory steel setup as it ages.
