2022-2026+ Hyundai IONIQ 5 / N CCB Big Brake Kit — Genuine Brembo FA042 Forged 6-Piston Caliper Front + Genuine Brembo GT4 Rear Setup
The IONIQ 5 is heavy, quick, and highly regenerative, so friction brakes can sit unused in daily driving and then see sharp heat load during mountain driving, repeated highway stops, or track sessions in the IONIQ 5 N. This StopFlex kit pairs 380mm front carbon-ceramic rotors with the Genuine Brembo FA042 Forged 6-Piston Caliper, then matches the rear with 355mm carbon-ceramic rotors and Brembo 4-piston options to control heat, reduce iron dust, and cut rotating unsprung mass. Every bracket, rotor-hat offset, and caliper position is engineered after the customer’s exact IONIQ 5 or IONIQ 5 N trim and wheel package are confirmed.
- 380mm is the largest rotor in this IONIQ 5 / N kit, so 19-inch wheels are the minimum; wheels under 19 inches will not clear, and spoke clearance still must be checked.
- Front axle uses the exact Genuine Brembo FA042 Forged 6-Piston Caliper with a 380mm carbon-ceramic rotor, not a repainted factory sliding caliper.
- Rear axle is matched with 355mm carbon-ceramic rotors and V4, GT4, or GTS4 Brembo 4-piston options so the car is not converted into a front-heavy brake package.

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 upgrade uses the Genuine Brembo FA042 Forged 6-Piston Caliper, giving the IONIQ 5 / N a fixed multi-piston front layout for more even pad loading and a firmer response than a single-sided sliding caliper. Its Brembo provenance and forged construction make it a credible front caliper choice for a high-mass EV that can put repeated load into the front axle under hard braking. StopFlex positions this caliper around a 380mm carbon-ceramic rotor with trim-specific brackets and hat offsets rather than assuming all IONIQ 5 variants share the same mounting geometry.
Rear Caliper (Balance)
The rear upgrade uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 355mm carbon-ceramic rotors: V4 is the Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 is the Genuine Brembo GT | M4 4-Piston Caliper, and GTS4 is the Genuine Brembo GT | S4 4-Piston Caliper. The rear package is selected and engineered to support brake balance and rear-axle stability while preserving the vehicle’s required electronic parking brake function where applicable.
Front & rear, engineered together: The 380mm front and 355mm rear carbon-ceramic rotors are engineered as a system so piston area, rotor diameter, pad choice, and axle bias are considered together. That matters on the IONIQ 5 / N because a front-only conversion can add front torque and heat capacity without matching the rear contribution needed for stable hard braking.
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 both a standard IONIQ 5 and the IONIQ 5 N?
The kit can be built for the 2022-2026+ IONIQ 5 family and IONIQ 5 N, but it is not sold as a generic platform-wide bolt-on. StopFlex confirms your exact year, trim, hub geometry, knuckle/upright package, and wheel data before producing brackets, rotor hats, and caliper mounting hardware.
What wheels are required for the 380mm front rotor?
The 380mm front rotor requires at least a 19-inch wheel. Diameter alone is not enough: the Genuine Brembo FA042 Forged 6-Piston Caliper also needs spoke clearance, so StopFlex checks wheel width, offset, barrel shape, and spoke profile before finalizing the kit.
Will the electronic parking brake still work?
Yes, the IONIQ 5 uses a factory Electronic Parking Brake, so rear fitment must be engineered around EPB function rather than treated like a simple hydraulic-only rear caliper swap. StopFlex confirms the rear configuration and EPB requirements for the exact trim before the kit is built.
Why switch this IONIQ 5 / N to carbon-ceramic brakes?
Carbon-ceramic rotors reduce iron brake dust, cut rotating unsprung mass, and tolerate repeated heat cycles better than conventional iron rotors. On an IONIQ 5 or IONIQ 5 N, the payoff is cleaner open wheels, improved thermal reserve for repeated high-speed stops, and a brake package sized around 380mm front and 355mm rear rotors.
