2015-2023 Skoda Superb / iV (3V) CCB Big Brake Kit — Genuine Alcon RC6 6-Piston Caliper Front + Genuine Alcon RC4 4-Piston Caliper Rear Setup
The 2015-2023 Skoda Superb / iV (3V) is a heavy, long-wheelbase MQB sedan or estate, so repeated high-speed braking can expose the heat limits, dust, and steering-weight penalty of the factory iron setup. This StopFlex kit replaces the factory braking package with 380 mm carbon-ceramic rotors, Genuine Alcon RC6 6-Piston Caliper front calipers, and Genuine Alcon RC4 4-Piston Caliper rear calipers engineered to the customer's exact Superb 3V trim. The payoff is higher thermal capacity, lower brake dust, reduced rotating and unsprung mass versus comparable iron hardware, and fitment specified around the confirmed knuckle, hub, rotor-hat offset, EPB layout, and wheel clearance.
- 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels on the Superb 3V; inner barrel and spoke clearance must still be checked before production.
- The kit uses a Genuine Alcon RC6 6-Piston Caliper at the front and a Genuine Alcon RC4 4-Piston Caliper at the rear, matched to carbon-ceramic pads, hats, hardware, and lines.
- Superb 3V and Superb iV trims can differ in weight, brake electronics, hub details, and wheel fitment, so StopFlex engineers the brackets and rotor-hat offsets to the confirmed vehicle rather than assuming MQB interchangeability.

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 380 mm carbon-ceramic rotor a broad, stable clamping footprint for repeatable pedal response under high thermal load. Alcon is a known motorsport and performance brake supplier, and this genuine caliper choice gives the Superb 3V a credible fixed-caliper front upgrade rather than an unbranded casting. StopFlex pairs the caliper with vehicle-specific brackets, carbon-ceramic pads, hats, hardware, and lines after the exact trim and wheel package are confirmed.
Rear Caliper (Balance)
The rear axle uses the Genuine Alcon RC4 4-Piston Caliper with a 380 mm carbon-ceramic rotor to keep rear torque contribution and chassis stability aligned with the stronger front system. On Superb 3V models equipped with the factory electronic parking brake, the rear package is engineered around EPB retention rather than deleting the parking-brake function.
Front & rear, engineered together: This kit is specified as a complete front-and-rear brake system so piston area, rotor diameter, pad compound, and hydraulic behavior can be matched as a package. That matters on the Superb 3V because a front-only big brake change can shift brake bias, ABS intervention, and rear stability away from the calibration expected by the chassis.
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 kit fit my exact Skoda Superb 3V trim?
Fitment is confirmed per car, not assumed from the Superb 3V chassis code. StopFlex verifies the exact trim, drivetrain, hub geometry, knuckle/upright details, and wheel data before specifying brackets, rotor-hat offsets, and caliper mounting.
What wheel size do I need for the 380 mm carbon-ceramic rotors?
The 380 mm rotor package requires 19 inch or larger wheels. Wheels under 19 inch will not clear the rotor, and 19 inch wheels still need spoke and inner-barrel clearance checked against the Genuine Alcon RC6 6-Piston Caliper.
Will the electronic parking brake still work?
Yes, when the customer's Superb 3V is equipped with the factory EPB, the rear kit is engineered to retain EPB function rather than converting the car to a manual parking brake. Final EPB details are confirmed from the exact model and trim before production.
Why choose carbon-ceramic brakes on a Superb instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass while adding heat capacity for repeated high-speed stops. On a large Superb or Superb iV, that helps address the weight and thermal load that make factory iron brakes feel dusty, heavy, or inconsistent during aggressive road use.
