2004-2026+ Skoda Octavia / vRS (1Z/5E/NX) CCB Big Brake Kit — Genuine Alcon RC6 6-Piston Caliper Front + Genuine Alcon RC4 4-Piston Caliper Rear Setup
Octavia and vRS owners usually reach this page after repeated heat fade, rotor cracking, heavy brake dust, or a wheel upgrade that exposes the factory iron brakes. This StopFlex kit pairs 380mm carbon-ceramic rotors with a Genuine Alcon RC6 6-Piston Caliper front package and Genuine Alcon RC4 4-Piston Caliper rear package to add thermal capacity while reducing rotating and unsprung mass versus comparable iron hardware. Every 1Z, 5E, or NX order is built around the exact trim, hub geometry, knuckle package, and wheel clearance data, not a platform-wide assumption.
- The largest rotor in this Octavia/vRS package is 380mm front and rear, so 19-inch wheels are the minimum and spoke clearance must be checked before production.
- Front braking is handled by the Genuine Alcon RC6 6-Piston Caliper with a 380mm carbon-ceramic rotor, targeting the heat load produced by tuned 2.0 TSI vRS street and track use.
- The 2004-2026+ Octavia range spans 1Z, 5E, and NX chassis generations, so StopFlex matches brackets and rotor-hat offsets to the confirmed car rather than assuming one shared VW Group fitment.

| Minimum wheel size | 19" (for the 380 mm front rotor) |
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 Alcon RC6 6-Piston Caliper, giving the 380mm carbon-ceramic rotor a broad, stable clamping interface for consistent pedal response under repeated high-speed stops. Alcon is a known performance brake manufacturer, and this genuine caliper selection gives the kit a proven motorsport-style foundation rather than an unbranded multi-piston casting. StopFlex engineers the front bracket, rotor hat, and line routing around the customer's exact Octavia or vRS trim.
Rear Caliper (Balance)
The rear axle uses the Genuine Alcon RC4 4-Piston Caliper with a matching 380mm carbon-ceramic rotor to support rear brake contribution without overloading the front axle. On NX cars equipped with a factory electronic parking brake, StopFlex verifies the rear configuration and EPB requirements before production.
Front & rear, engineered together: A 380mm front-only conversion can change pedal feel and axle bias if the rear hardware is left behind. This kit is engineered as a front-and-rear system so the Alcon RC6 front and Alcon RC4 rear packages work with matched rotor diameter, pad selection, hat offset, and vehicle-specific mounting geometry.
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 fit my exact Skoda Octavia or vRS?
Fitment is confirmed against your exact 1Z, 5E, or NX model, trim, drivetrain, hub/knuckle package, and wheel data before the kit is built. StopFlex does not treat all Octavia or MQB variants as the same bracket and hat-offset fitment.
What wheel size do I need for the 380mm kit?
The 380mm rotor package requires at least 19-inch wheels. Barrel clearance is only one part of the check; spoke shape, wheel offset, and caliper face clearance must also be verified for the Genuine Alcon RC6 front caliper.
Will the electronic parking brake still work?
Some 2020-on Octavia NX variants have a factory electronic parking brake, while earlier 1Z and many 5E cars use a manual parking brake. StopFlex confirms your rear parking-brake layout before production so the rear package is specified for your car rather than assumed.
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 a similar-size iron setup. On an Octavia vRS used for fast road or track driving, the 380mm rotor and Alcon caliper package adds thermal margin without the dust and weight penalty of a large iron conversion.
