Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2006-2018 Mercedes-Benz / AMG (W463). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2006-2018 | Akebono OEM Audi RS 10-Piston (10N) Caliper / 420mm | Brembo OEM AUDI e-tron GT 4-Piston Caliper / 410mm | 21" |
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 420 mm rotor sets the minimum wheel size at 21" — 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
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.
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.
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.
Caliper Overview
Front Caliper
The front caliper is the Akebono OEM Audi RS 10-piston (10N) unit, clamping a 420mm carbon-ceramic rotor. Ten opposed pistons spread clamping load evenly across a long pad, which keeps pedal feel firm and consistent on a heavy W463 truck under repeated hard stops.
Rear Caliper
The rear runs the Brembo OEM Audi e-tron GT 4-piston caliper on a 410mm carbon-ceramic rotor, adding real rear thermal capacity for a vehicle of this mass. If your build needs a different rear configuration for parking-brake or hat clearance, we match it to your confirmed trim.
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.
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 fit my exact G-Wagon, or is it a generic W463 kit?
It is built for your confirmed trim, not the platform in general. G500, G550, G55, G63, and G65 can differ in hub geometry and wheel clearance, so we cut brackets and set rotor-hat offsets to match the car you tell us. We do not ship an assumed platform-wide bolt-on.
What wheels do I need to clear the 420mm front rotor?
The 420mm front rotor and Akebono 10-piston caliper require a minimum 21-inch wheel. Anything under 21 inches will not clear the caliper, and spoke shape matters too, so send us your wheel spec before ordering and we will confirm clearance.
How does carbon ceramic behave in winter and cold starts?
An untuned cold ceramic disc bites less than cold iron on the first stops. That is physics, not a fault. We tune both the pad compound and the disc's ceramic coating for cold operation, so cold-car feel now comes very close to warm feel. On the coldest first stops, leave a little extra following distance until the system is up to temperature.
Why upgrade over the factory brakes on a heavy G-Class?
The W463 is a heavy truck, and the pre-2019 factory iron setup, especially on non-AMG trims, can heat-soak and fade under sustained hard use. Carbon-ceramic rotors resist fade at high temperature and shed rotating mass, while the 10-piston front and 4-piston rear give consistent clamping the stock system cannot hold as it heats.
