2015-2021 Volkswagen Golf / GTI / R (Mk7/Mk7.5) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
Mk7 and Mk7.5 Golf, GTI, and Golf R owners usually reach this upgrade point after repeated iron-rotor heat checking, pad fade, heavy brake dust, or a wheel package that makes the factory brakes look undersized. This StopFlex kit uses 380 mm carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-piston front caliper options and matching Brembo V4 / GT4 / GTS4 4-piston rear options to add thermal capacity while reducing rotating mass versus comparable iron hardware. Fitment is engineered to the confirmed Golf, GTI, or Golf R trim, not assumed from the MQB platform, because knuckle, hub, bracket offset, and wheel-clearance details matter on this chassis.
- 380 mm front and rear carbon-ceramic rotors require 19-inch or larger wheels on Mk7/Mk7.5 Golf, GTI, and Golf R; spoke clearance must still be checked with the exact wheel model and offset.
- Front choices are V6, GT6, or GTS6 6-piston Brembo calipers, each paired with a 380 mm rotor for higher heat capacity than the factory Mk7/Mk7.5 iron setup.
- Each kit is built around the customer’s confirmed Golf, GTI, or Golf R trim so rotor-hat offset, caliper bracket geometry, and line routing are not treated as universal MQB fitment.

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 Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, giving the buyer a choice between V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, GT6 = Genuine Brembo GT | M6 6-Piston Caliper, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper, all matched to a 380 mm rotor. A 6-piston Brembo front caliper spreads pad pressure across the larger carbon-ceramic disc for more consistent clamping force and a firmer pedal during repeated high-speed stops. The caliper selection is based on genuine OEM-derived or Brembo GT-family hardware, with mounting adapted to the exact Mk7/Mk7.5 Golf, GTI, or Golf R trim.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with a 380 mm carbon-ceramic rotor: V4 = Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 = Genuine Brembo GT | M4 4-Piston Caliper, or GTS4 = Genuine Brembo GT | S4 4-Piston Caliper. The rear package is matched to the front system for braking stability, rear torque contribution, and parking-brake requirements confirmed during order review.
Front & rear, engineered together: A 380 mm front-only brake conversion can shift thermal and torque demand forward if the rear axle is left as an afterthought. StopFlex engineers the front and rear caliper brackets, rotor hats, pad compounds, and hydraulic layout together so the Golf, GTI, or Golf R keeps predictable brake balance under street, canyon, and track braking loads.
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 380 mm kit fit my exact Mk7 or Mk7.5 Golf, GTI, or Golf R?
Fitment is confirmed per vehicle, not by chassis name alone. StopFlex checks the exact model, trim, front knuckle/upright, hub geometry, wheel diameter, wheel offset, spoke clearance, and brake-line routing before building the brackets and rotor hats.
What wheel size do I need for the 380 mm Brembo carbon-ceramic setup?
The 380 mm front and rear rotors require 19-inch or larger wheels. Wheel diameter alone is not enough; the Brembo 6-piston front caliper also needs spoke clearance, so StopFlex verifies the wheel model, offset, and available barrel space before production.
Does this kit keep the factory parking brake on a Mk7 GTI or Golf R?
Most U.S. Mk7/Mk7.5 Golf, GTI, and Golf R cars use a manual cable handbrake, not an EPB motor on the rear caliper. StopFlex confirms the parking-brake hardware during order review and builds the rear solution around the customer’s exact configuration.
Why choose carbon-ceramic rotors instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass while tolerating repeated high-temperature use better than a same-size iron rotor. On a Golf R or tuned GTI that sees fast road or track work, the 380 mm rotor package adds heat capacity without the full weight penalty of oversized iron discs.
