2014-2021 BMW 2 Series / M2 (F22/F23/F87) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
F22/F23 2 Series and F87 M2 owners usually shop this kit after repeated iron-rotor heat stress, track fade, heavy brake dust on open wheels, or the cost of replacing high-performance brake hardware. This StopFlex kit pairs 380 mm front carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-piston caliper options and 355 mm rear carbon-ceramic rotors with Brembo V4 / GT4 / GTS4 4-piston caliper options. Each order is engineered around the buyer’s exact 228i, 230i, M235i, M240i, M2, M2 Competition, or M2 CS configuration, because F22/F23 standard models and F87 M cars do not share every knuckle, hub, offset, and wheel-clearance constraint.
- 380 mm front and 355 mm rear carbon-ceramic rotors add heat capacity for F22/F23/F87 track use while reducing the dust and mass associated with large iron brake packages.
- Front caliper choices are Brembo V6, GT6, or GTS6 6-piston units on the same 380 mm rotor diameter, so the buyer selects the caliper family without changing the required 19-inch minimum wheel size.
- F22/F23 2 Series trims and F87 M2 variants are measured as separate applications; StopFlex does not assume that an M240i, M2 Competition, and 230i use the same bracket geometry or rotor-hat offset.

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, giving the car a fixed 6-piston layout for controlled pad loading, clamping force, and pedal consistency on a 380 mm rotor. The buyer chooses V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper — 380 mm rotor, GT6 = Genuine Brembo GT | M6 6-Piston Caliper — 380 mm rotor, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper — 380 mm rotor. Each option is a genuine Brembo caliper family, not an unbranded casting, and is matched to StopFlex carbon-ceramic rotor hats, brackets, pads, lines, and hardware for the confirmed BMW trim.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 355 mm carbon-ceramic rotors to support rear brake contribution without destabilizing the short-wheelbase F22/F23/F87 chassis under trail braking or hard straight-line stops. Rear choices are V4 = Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 = Genuine Brembo GT | M4 4-Piston Caliper, or GTS4 = Genuine Brembo GT | S4 4-Piston Caliper, each paired with the 355 mm rear rotor.
Front & rear, engineered together: StopFlex engineers the 380 mm front and 355 mm rear package as one brake system, so piston area, rotor diameter, pad selection, bracket location, and hat offset are considered together. That matters on the 2 Series/M2 family because a front-only large-caliper conversion can shift brake torque forward and leave the rear axle under-used during repeated high-speed stops.
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.

FAQ
Will this kit fit my exact F22, F23, or F87 trim?
Fitment is confirmed per car, not assumed from the chassis code. StopFlex verifies the exact model, trim, drivetrain, factory brake package, wheel specs, and intended caliper choice before machining the brackets and rotor hats, because a 230i, M240i, M2, M2 Competition, and M2 CS can differ in upright geometry and wheel clearance.
What wheel size do I need for the 380 mm front rotor?
The minimum wheel diameter is 19 inches because the largest front rotor in this kit is 380 mm. Wheel diameter alone is not enough; spoke shape, barrel profile, offset, and spacer use also affect clearance over the Brembo V6 / GT6 / GTS6 6-piston front caliper.
Will my parking brake still work?
This F22/F23/F87 application does not use a factory electronic parking brake. The car has a manual cable handbrake system, so rear fitment is handled around the mechanical parking-brake layout rather than EPB motor integration.
Why choose carbon-ceramic instead of another iron big brake kit?
For a 2 Series or M2 that sees repeated high-speed braking, carbon-ceramic rotors reduce brake dust, cut rotating and unsprung mass compared with equivalent large iron rotors, and resist heat-related fade when paired with the correct pads. The 380 mm front and 355 mm rear layout also gives the car more thermal capacity than a stock-size replacement setup.
