2022-2026+ BMW 2 Series / M2 (G42/G87) CCB Big Brake Kit — Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper Front + Genuine Brembo GT4 Rear Setup
G42 2 Series and G87 M2 owners usually shop carbon-ceramic brakes after repeated iron-rotor heat cycles, brake dust on open wheels, or the cost of replacing high-performance brake hardware after track use. This StopFlex kit uses a 380 mm front carbon-ceramic rotor with the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper, then pairs it with 355 mm rear carbon-ceramic rotors and Brembo V4 / GT4 / GTS4 4-piston rear options. Every kit is built around the confirmed G42 or G87 trim so the brackets, rotor-hat offsets, caliper position, lines, and wheel-clearance targets match the actual car, not just the platform code.
- 380 mm is the largest rotor in this kit, so 19-inch wheels are the minimum; barrel and spoke clearance must still be checked against the chosen wheel offset and design.
- Front braking is handled by the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper on a 380 mm StopFlex carbon-ceramic rotor for higher heat capacity than a smaller factory-style iron package.
- Rear fitment uses a 355 mm carbon-ceramic rotor with V4, GT4, or GTS4 Brembo 4-piston options so the G42/G87 rear axle is matched to the front conversion rather than left as an unrelated add-on.

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 Brembo-built OEM performance caliper selected for its six-piston layout and stable pad loading on a 380 mm rotor. The six-piston design spreads clamping force across a larger pad area than a smaller sliding-caliper layout, helping pedal consistency during repeated high-speed stops. StopFlex adapts this caliper to the confirmed BMW G42 or G87 trim with trim-specific brackets, hat offsets, and brake lines rather than treating all 2 Series and M2 variants as mechanically identical.
Rear Caliper (Balance)
The rear axle can be configured with Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on a 355 mm 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 supports brake-balance tuning and straight-line stability under trail braking while preserving the correct parking-brake solution for the confirmed G42/G87 configuration.
Front & rear, engineered together: A 380 mm 6-piston front conversion changes front torque capacity, thermal mass, and pedal response, so the 355 mm rear carbon-ceramic package is engineered as part of the same system. StopFlex sizes rotor hats, brackets, lines, and caliper mounting around the exact trim so the car does not end up with a front-heavy mismatch or rear hardware that conflicts with the factory parking-brake layout.
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.

- Custom caliper logo
- Custom rotor hat color
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 230i, M240i, or G87 M2?
Fitment is confirmed by exact model, trim, factory brake package, and wheel specification before production. G42 standard-performance trims and the G87 M2 can differ in front knuckles/uprights, hub geometry, and wheel ET clearance, so StopFlex builds the brackets and rotor-hat offsets for the individual car rather than claiming a universal G42/G87 bolt-on fit.
What wheel size do I need for the 380 mm front rotor?
The 380 mm front rotor requires 19-inch or larger wheels; wheels under 19 inches will not clear the rotor. Spoke clearance is also checked because the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper can need more outward room than the factory caliper depending on wheel offset and spoke shape.
Will the electronic parking brake still work?
Yes, the rear package is specified around the BMW G42/G87 electronic parking-brake layout during fitment confirmation. The correct rear caliper option, parking-brake solution, bracket geometry, and line routing are matched to the confirmed trim before the kit is built.
Why choose carbon-ceramic instead of another iron big-brake kit?
Carbon-ceramic rotors reduce brake dust, cut rotating and unsprung mass, and resist heat-related fade during repeated hard stops better than a comparable iron rotor package. For this kit, the 380 mm front and 355 mm rear carbon-ceramic rotors are paired with fixed Brembo calipers to give the G42/G87 owner a lower-dust, track-capable system without relying on platform-generic hardware.
