2006-2018 Mercedes-Benz G500 / G550 / G55 / G63 / G65 (W463) CCB Big Brake Kit — Genuine Akebono OEM Porsche 10-Piston (10N) Caliper Front + Genuine Brembo OEM Porsche 19Z 4-Piston Caliper Rear Setup
The 2006-2018 W463 G-Class is heavy, tall, and hard on front brakes, especially when larger wheels, tuned AMG power, towing, or repeated mountain braking expose the limits of the factory iron setup. This StopFlex kit pairs a 420mm front carbon-ceramic rotor with a Genuine Akebono OEM Porsche 10-Piston (10N) Caliper and a 410mm rear carbon-ceramic rotor with a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper to add heat capacity, reduce brake dust, and remove rotating mass at all four corners. Each kit is engineered to the confirmed G500, G550, G55, G63, or G65 trim rather than treated as a generic W463 bolt-on.
- 420mm front and 410mm rear carbon-ceramic rotors require 21 inch or larger wheels; wheels under 21 inches will not clear the front package, and spoke clearance must still be checked.
- The front axle uses the exact Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, giving this heavy W463 a large pad sweep area and firm multi-piston pressure distribution.
- G500/G550, G55, G63, and G65 W463 variants can differ in brake packaging, knuckle/upright details, hub geometry, and wheel offset, so StopFlex builds brackets and hat offsets for the confirmed trim.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 420 mm front rotor, so the minimum wheel size is 21". Wheels under 21" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, a 10-piston fixed caliper selected to spread clamp load across a large pad area on the 420mm front rotor. Its OEM Porsche provenance matters because the caliper was developed for high-output vehicle braking loads rather than styled as an aftermarket look-alike. The fixed aluminum multi-piston construction supports consistent pedal response when the W463’s weight and high center of gravity put repeated load into the front axle.
Rear Caliper (Balance)
The rear axle uses a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper on a 410mm carbon-ceramic rotor to keep rear torque, pad area, and thermal capacity matched to the front upgrade. This generation W463 does not use a factory electronic parking brake, so the rear package is engineered around the vehicle’s mechanical parking-brake arrangement rather than an EPB motor caliper.
Front & rear, engineered together: The 420mm front and 410mm rear package is engineered as a complete system so brake torque, thermal capacity, and pedal response are matched across both axles. On a short-wheelbase-feeling, high-center-of-gravity SUV like the W463, a front-only big brake conversion can disturb rear contribution and stability; StopFlex specifies front and rear hardware together for the confirmed trim.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak 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.
Street / Track-Day / Motorsport Rotor Options
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.

FAQ
Will this kit fit my exact G500, G550, G55, G63, or G65?
Fitment is not assumed from the W463 chassis code. StopFlex confirms your exact model year, trim, hub and knuckle configuration, wheel size, wheel offset, and spoke clearance before engineering the brackets, rotor-hat offsets, lines, and hardware.
What wheel size is required for the 420mm front rotor?
The 420mm front carbon-ceramic rotor requires 21 inch or larger wheels. Wheels under 21 inches will not clear the front package, and some 21 inch wheels still need a spoke-clearance check against the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper.
Will the parking brake still work?
Yes, the kit is designed around the 2006-2018 W463 mechanical parking-brake system, not an EPB motor-on-caliper layout. The rear carbon-ceramic package must preserve the vehicle’s drum-in-hat parking-brake function when the final rear hat is specified.
Why choose carbon ceramic on a W463 instead of another iron brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass while adding high-temperature fade resistance for a heavy G-Class driven aggressively, loaded, or repeatedly braked downhill. The 420mm front and 410mm rear sizing also gives the W463 the visual rotor fill expected behind 21 inch or larger wheels.
