2024-2026+ BMW I5 (G60/G61) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
The 2024-2026+ BMW i5 G60/G61 is heavy, quick, and regenerative, so owners shopping this kit are usually trying to reduce iron-rotor heat load, brake dust, and unsprung weight without guessing at fitment. StopFlex pairs a 380 mm front carbon-ceramic rotor with Brembo V6 / GT6 / GTS6 6-piston front caliper options and matched 4-piston rear options, then engineers the brackets, hats, lines, and hardware for the confirmed trim. The payoff is higher thermal stability on repeated high-speed stops, cleaner open wheels, and a kit that is not treated as a generic 5-Series platform swap.
- 380 mm is the largest rotor in this BMW i5 G60/G61 kit, so 19-inch wheels are the minimum; spoke clearance still has to be checked against the selected Brembo caliper profile.
- Front choices are V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper with 380 mm rotor, GT6 = Genuine Brembo GT | M6 6-Piston Caliper with 380 mm rotor, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper with 380 mm rotor.
- The rear axle can be matched with Brembo V4, GT4, or GTS4 4-piston calipers using 355 or 380 mm carbon-ceramic rotors, selected around the car’s brake bias, EPB requirements, and wheel 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 axle uses Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, all paired with a 380 mm carbon-ceramic rotor. Six opposed pistons spread clamping load across the pad for more stable pedal response and better heat management than a smaller single-axle upgrade. The buyer chooses among Genuine Brembo OEM Cadillac CTS-V 6-Piston, Genuine Brembo GT | M6 6-Piston, or Genuine Brembo GT | S6 6-Piston hardware, so the build is based on known Brembo architecture rather than an unbranded casting.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with 355 or 380 mm carbon-ceramic rotors, so rear torque is matched to the selected front 380 mm setup instead of left stock by default. Because the BMW i5 uses a factory electronic parking brake and Auto Hold switch, rear fitment is engineered around retaining the required EPB function for the confirmed trim.
Front & rear, engineered together: A 380 mm 6-piston front conversion changes front brake torque, thermal capacity, and pedal behavior, so the rear package is selected as part of the same system. StopFlex matches front and rear rotor diameter, hat offset, bracket geometry, pad compound, and line routing to the exact BMW i5 trim to avoid the bias and stability issues of a front-only mismatch.
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 2024-2026+ BMW i5 trim?
Only after confirmation. StopFlex does not assume every G60/G61 BMW i5 shares the same knuckle, hub position, rotor-hat offset, or wheel clearance; the brackets, hats, lines, and caliper mounts are specified for your exact trim and brake package before production.
What wheel size do I need for the 380 mm front kit?
The 380 mm front rotor requires at least a 19-inch wheel. Barrel clearance is only one check; spoke shape, wheel offset, and the chosen Brembo V6, GT6, or GTS6 caliper profile must also be verified before the kit is built.
Will the electronic parking brake and Auto Hold still work?
The BMW i5 uses an electronic parking brake with Auto Hold, so the rear setup is engineered around EPB retention where rear calipers are included. StopFlex confirms the exact rear brake configuration before specifying the Brembo V4, GT4, or GTS4 rear option.
Why switch this i5 from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, cut rotating and unsprung mass, and hold temperature more consistently during repeated high-speed stops. On a heavy electric sedan like the i5, those benefits are most useful for owners who drive hard, use open wheels, or want less rotor and pad dust than the factory iron setup.
