2003-2010 Mercedes-Benz CLK350 / CLK500 / CLK550 / CLK63 (C209/A209) CCB Big Brake Kit — Genuine OEM AMG 6-Piston Caliper Front + Genuine OEM AMG 4-Piston Caliper Rear Setup
C209/A209 CLK owners usually shop carbon-ceramic brakes when iron rotors and pads cannot keep heat, dust and pedal feel under control on a heavy V8 or AMG-driven car. This StopFlex kit pairs a 390 mm front carbon-ceramic rotor with the Genuine OEM AMG 6-Piston Caliper and a 380 mm rear rotor with the Genuine OEM AMG 4-Piston Caliper, giving the car more thermal capacity, lower brake dust and a larger visual package behind 20-inch or larger wheels. Each order is engineered for the buyer’s confirmed CLK350, CLK500, CLK550 or CLK63 trim, because bracket position, hat offset, hub geometry and wheel clearance are not treated as platform-wide assumptions.
- 390 mm front carbon-ceramic rotors require 20-inch or larger wheels on the C209/A209 CLK, and spoke clearance must still be checked against the Genuine OEM AMG 6-Piston Caliper.
- The kit uses a 380 mm rear carbon-ceramic rotor with the Genuine OEM AMG 4-Piston Caliper so the rear axle is upgraded with the front instead of being left as a heat and bias mismatch.
- CLK350, CLK500, CLK550 and CLK63 applications are confirmed by exact trim before production, since the AMG variant and standard models can differ in brake mounting, upright geometry and wheel offset clearance.

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 390 mm front rotor, so the minimum wheel size is 20". Wheels under 20" 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 axle uses the Genuine OEM AMG 6-Piston Caliper, giving the 390 mm rotor a wide, multi-piston clamp pattern for consistent pad loading and a firm pedal response. Its OEM AMG provenance matters on a C209/A209 CLK because the caliper architecture was developed for high-output Mercedes applications rather than being a generic aftermarket casting. StopFlex engineers the mounting hardware, rotor hat and line package around this exact caliper and the customer’s confirmed trim.
Rear Caliper (Balance)
The rear axle uses the Genuine OEM AMG 4-Piston Caliper with a 380 mm carbon-ceramic rotor to keep rear braking contribution stable during high-speed deceleration. This rear package supports brake balance instead of leaving the front 390 mm conversion to carry the system alone.
Front & rear, engineered together: The 390 mm front and 380 mm rear carbon-ceramic package is specified as a matched system so piston area, rotor diameter, pad behavior and hat offset are considered together. That matters on the CLK350, CLK500, CLK550 and CLK63 because a front-only conversion can change pedal travel, ABS behavior and rear stability if the rear axle is not matched to the new front torque capacity.
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 CLK350, CLK500, CLK550 or CLK63?
StopFlex does not treat C209/A209 as a universal fitment claim. Your exact model year, body style, trim, hub/brake configuration and wheel data are confirmed before brackets, rotor-hat offsets and caliper mounting are finalized.
What wheel size do I need for the 390 mm front setup?
The 390 mm front rotor requires 20-inch or larger wheels. Wheel diameter alone is not enough; spoke shape, barrel profile and offset must clear the Genuine OEM AMG 6-Piston Caliper before the kit is approved.
Does this car have an electronic parking brake that needs to be retained?
No. The 2003-2010 CLK350, CLK500, CLK550 and CLK63 C209/A209 platform uses a mechanical parking brake system, so there is no factory EPB motor or auto-hold rear caliper function to preserve.
Why choose carbon-ceramic instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust, resist heat-related fade and cut rotating mass compared with same-size iron hardware. On a CLK with 390 mm front and 380 mm rear rotors, that helps repeated high-speed stops while keeping the open-wheel appearance cleaner.
