2022-2026+ Hyundai IONIQ 5 / N CCB Big Brake Kit — Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper Front + Genuine Brembo GT4 Rear Setup
The 2022-2026+ Hyundai IONIQ 5 / N is heavy, quick, and regenerative braking can leave the friction brakes underused on the street but heavily loaded when the car is driven hard. This StopFlex kit replaces the friction package with 380 mm front carbon-ceramic rotors clamped by the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper and 355 mm rear carbon-ceramic rotors with Brembo V4 / GT4 / GTS4 4-piston options. The result is more thermal capacity for repeated stops, lower iron dust on open EV wheels, reduced unsprung mass versus comparable iron hardware, and fitment engineered from the customer’s confirmed IONIQ 5 or IONIQ 5 N trim instead of assumed from the E-GMP platform.
- 380 mm front rotors require 19-inch or larger wheels; IONIQ 5 N 21-inch factory wheels and standard IONIQ 5 19/20-inch wheel packages still require spoke-clearance verification.
- Front hardware uses the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper with a 380 mm carbon-ceramic rotor, not a generic painted sliding-caliper conversion.
- Rear choices are V4, GT4, or GTS4 Brembo 4-piston calipers, each matched to a 355 mm carbon-ceramic rotor and engineered around the IONIQ 5’s factory EPB requirements.

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 Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper, a fixed Brembo unit chosen for its piston count, stiffness, and OEM performance-car provenance. Six opposed pistons distribute clamping load across the pad face, improving pedal consistency and pressure control on a heavy EV during repeated high-speed stops. StopFlex pairs this caliper with a 380 mm carbon-ceramic rotor, vehicle-specific hat offset, and trim-specific mounting hardware for the confirmed IONIQ 5 or IONIQ 5 N configuration.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on a 355 mm carbon-ceramic rotor: V4 = Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 = Genuine Brembo GT | M4 4-Piston Caliper, and GTS4 = Genuine Brembo GT | S4 4-Piston Caliper. The rear package is engineered to support brake balance, braking stability, and the IONIQ 5’s factory EPB architecture instead of treating the rear as cosmetic hardware.
Front & rear, engineered together: The 380 mm front and 355 mm rear carbon-ceramic rotors are specified as a matched system so front torque capacity, rear contribution, ABS behavior, and pedal travel stay coordinated. This matters on the IONIQ 5 / N because adding only a large front caliper can shift the brake balance forward and leave the rear axle underutilized during hard friction-brake events.
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+ IONIQ 5 or IONIQ 5 N trim?
Fitment is confirmed by exact trim before production. StopFlex does not assume that a standard IONIQ 5 and IONIQ 5 N use the same knuckle, hub, offset, or wheel-clearance requirements; brackets, rotor-hat offsets, caliper mounting, lines, and hardware are matched to the customer’s verified car.
What wheels are required for the 380 mm front rotor?
The 380 mm front rotor requires 19-inch or larger wheels, and wheels under 19 inches will not clear the package. Spoke clearance still has to be checked because the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper is wider than the factory-style sliding caliper envelope.
Will the electronic parking brake still work?
The IONIQ 5 / N uses a factory Electronic Parking Brake, so the rear configuration must be handled as part of the brake engineering, not as an afterthought. StopFlex verifies the exact rear setup and EPB requirements before finalizing the Brembo V4, GT4, or GTS4 355 mm rear package.
Why switch an IONIQ 5 / N to carbon-ceramic brakes?
Carbon-ceramic rotors target the problems that matter on a heavy, high-torque EV: heat control during repeated friction stops, reduced unsprung mass versus comparable iron rotor hardware, and far less visible brake dust on open wheels. The kit keeps the front and rear rotor sizes defined at 380 mm and 355 mm, with pad compound and hardware selected for the customer’s street or track use.
