Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2006-2013 Mercedes-Benz R-Class / AMG (W251). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2006-2013 | Alcon RC6 6-Piston Caliper / 380mm | Alcon RC4 4-Piston Caliper / 380mm | 19" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — 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
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.
Caliper Overview
Front Caliper
The front runs an Alcon RC6 6-piston caliper on the 380mm carbon-ceramic rotor. Six pistons spread clamping load evenly across a long pad, so the pedal stays firm and consistent even after repeated stops with a heavy R-Class up front.
Rear Caliper
The rear uses an Alcon RC4 4-piston caliper on a 380mm carbon-ceramic rotor. This adds real rear thermal capacity to a vehicle that carries weight rearward when loaded, keeping brake balance stable on long descents.
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
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.
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 kit actually fit my exact R-Class, not just a W251?
We build each kit to your confirmed trim, not to the platform. An R63 AMG uses different front knuckles, hub geometry, and wheel clearance than an R350 or R500, so the brackets, rotor-hat offsets, and caliper mounting are cut for your specific car. We confirm your VIN and trim before anything ships.
What wheels do I need to clear these brakes?
The 380mm front and rear rotors require a minimum 19-inch wheel. Diameter alone isn't enough; spoke shape and inner barrel clearance around the RC6 front caliper also matter, so send us your wheel details and we'll verify clearance before you buy.
How do carbon-ceramic brakes behave in winter on a cold morning?
An untuned cold ceramic disc bites less than cold iron on the first stops. That's physics, not a fault. We've tuned both the pad compound and the disc's ceramic coating for cold starts, so cold-car feel now comes very close to warm summer feel. Leave a little extra following distance on the first stops of a freezing morning and you're set.
Is this a real upgrade over the factory R-Class brakes?
Yes. The stock brakes struggle with a vehicle this heavy, especially loaded or towing. You get 380mm carbon-ceramic rotors front and rear, Alcon RC6 6-piston front and RC4 4-piston rear calipers, a carbon-ceramic-specific low-metallic pad (about 0.44 friction, fade-resistant to roughly 750 °C), plus hats, hardware, and lines. Weight comes off the corners and heat capacity goes up.
