2022-2026+ Volkswagen Golf / GTI / R (Mk8) CCB Big Brake Kit — Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper Front + Genuine AP Racing CP9541 Radi-CAL II 4-Piston Caliper Rear Setup
Mk8 Golf GTI and Golf R owners usually reach this point after the factory iron brakes run hot during repeated high-speed stops, create heavy wheel dust, or develop vibration after track use. This StopFlex kit pairs 380mm carbon-ceramic rotors with a Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper up front and a Genuine AP Racing CP9541 Radi-CAL II 4-Piston Caliper at the rear for higher heat capacity, stable pedal response and reduced rotating mass versus comparable iron hardware. Every kit is built around the confirmed Mk8 trim, wheel package and hub geometry, so rotor-hat offset and bracket design are matched to the actual car rather than assumed from the Golf platform name.
- 380mm front and rear carbon-ceramic rotors require 19 inch or larger wheels; wheels under 19 inches will not clear the rotor package, and spoke clearance must still be checked.
- The front axle uses the Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper with a 380mm carbon-ceramic rotor for repeated heat cycles beyond the factory Mk8 Golf GTI/R iron-brake envelope.
- Mk8 Golf, GTI and R trims can differ in brake packaging and wheel offset, so StopFlex engineers the brackets and rotor-hat offsets to the customer's exact confirmed trim rather than selling one platform-wide bracket set.

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 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" 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 AP Racing CP9560 Radi-CAL II 6-Piston Caliper, giving the Mk8 Golf platform a six-piston fixed-caliper layout to distribute clamping force across the pad and support a firmer, more consistent pedal under repeated braking. AP Racing is a known motorsport brake manufacturer, and the Radi-CAL II architecture is selected here for a rigid, lightweight performance-caliper package paired to the 380mm StopFlex carbon-ceramic rotor.
Rear Caliper (Balance)
The rear axle uses the Genuine AP Racing CP9541 Radi-CAL II 4-Piston Caliper with a matching 380mm carbon-ceramic rotor so rear torque contribution is engineered into the complete kit instead of left to the factory rear brakes. Because Mk8 Golf/GTI/R models use an electronic parking brake, EPB integration must be confirmed during the build specification.
Front & rear, engineered together: The 6-piston front and 4-piston rear AP Racing calipers are specified together so piston area, pad selection, rotor diameter and rear contribution can be balanced as a system. On a short-wheelbase hot hatch like the Mk8 Golf GTI/R, matching the rear conversion to the front upgrade helps maintain stability during trail braking and repeated high-speed stops.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this 380mm kit fit my exact Mk8 Golf, GTI or Golf R?
Fitment is confirmed by exact year, trim, front knuckle/upright, hub geometry and wheel specifications before production. StopFlex does not treat every Mk8 Golf, GTI and R as the same brake package; brackets, rotor-hat offsets and caliper mounting are built for the confirmed car.
What wheel size do I need for this kit?
The 380mm front and rear rotors require 19 inch or larger wheels. Wheel diameter alone is not enough: spoke shape, barrel profile and offset must be checked against the Genuine AP Racing CP9560 front caliper and CP9541 rear caliper.
Will the electronic parking brake still work?
Mk8 Golf/GTI/R models use an electronic parking brake, so EPB compatibility is handled during the rear kit specification. The order process must confirm the exact rear-brake and EPB configuration before the rear AP Racing conversion is released for production.
Why move from the factory iron brakes to carbon ceramic on this car?
The Mk8 GTI and Golf R are heavy enough and quick enough to overwork factory iron brakes during repeated high-speed stops or track sessions. Carbon-ceramic rotors reduce brake dust, resist heat-related fade and remove rotating mass while the AP Racing calipers improve pad support and pedal consistency.
