2022-2026+ BMW iX (I20) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
The BMW iX I20 is a heavy electric SUV, so repeated high-speed stops load the front axle hard even with regenerative braking handling part of daily deceleration. This StopFlex kit pairs a 380 mm front carbon-ceramic rotor with Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, then matches the rear with Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 355 or 380 mm carbon-ceramic rotors. The result targets lower brake dust, reduced rotating mass, stronger thermal capacity, and confirmed fitment for the customer’s exact iX trim and wheel package.
- 380 mm is the largest rotor in this iX I20 kit, so 19-inch wheels are the minimum; spoke clearance and wheel offset still must be checked before production.
- Front choices are V6, GT6, or GTS6 6-piston Brembo calipers on a 380 mm carbon-ceramic rotor, built for the iX’s heavy EV braking load.
- Rear choices are V4, GT4, or GTS4 4-piston Brembo calipers with 355 or 380 mm carbon-ceramic rotors to keep rear contribution matched to the front upgrade.

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, with each option paired to a 380 mm carbon-ceramic rotor: V6 is a Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, GT6 is a Genuine Brembo GT | M6 6-Piston Caliper, and GTS6 is a Genuine Brembo GT | S6 6-Piston Caliper. The 6-piston layout spreads pad pressure across the rotor face for consistent clamping and pedal response during repeated stops. Each option is a genuine Brembo fixed-caliper architecture selected for this kit, not a cosmetic caliper cover or generic casting.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with 355 or 380 mm carbon-ceramic rotors, matched to support brake bias and stability under heavy deceleration. Because the BMW iX uses a factory electronic parking brake, rear execution is engineered around EPB compatibility during order confirmation.
Front & rear, engineered together: This is engineered as a front-and-rear system so rotor diameter, caliper piston area, pad compound, and rear parking-brake requirements are treated together. On an iX, that matters because a front-only mismatch can change pedal feel and stability behavior more than the factory integrated braking system expects.
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 2022–2026+ BMW iX trim?
Fitment is confirmed per vehicle, not assumed from the I20 chassis code. StopFlex verifies the customer’s exact iX trim, wheel package, hub geometry, and brake configuration before machining brackets, rotor hats, and caliper mounts.
What wheel size do I need for the 380 mm front rotor?
The 380 mm rotor requires at least a 19-inch wheel. Wheel offset and spoke shape also matter, so StopFlex checks wheel clearance before finalizing the Brembo 6-piston front setup.
Will the factory electronic parking brake still work?
Yes, the rear package is engineered around the BMW iX factory electronic parking brake. EPB compatibility is confirmed during order review because rear caliper choice, rotor size, and parking-brake integration must match the exact car.
Why choose carbon-ceramic rotors on an electric iX instead of iron rotors?
Carbon-ceramic rotors reduce brake dust on open EV wheels, cut rotating mass, and tolerate repeated heat cycles better than conventional iron rotors. On the iX, that matters most during mountain driving, repeated highway stops, or spirited use where the vehicle’s weight can overwhelm the friction brakes after regeneration tapers off.
