Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2022-2026+ BMW 2 Series / M2 (G42/G87). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2022-2026+ | Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper / 400mm |
Option 1: Brembo OEM Cadillac CTS-V 4-Piston Caliper — 370 mm rotor Option 2: Brembo GT | M4 4-Piston Caliper — 370 mm rotor Option 3: Brembo GT | S4 4-Piston Caliper — 370 mm rotor |
20" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.
The 400 mm rotor sets the minimum wheel size at 20" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front runs the Brembo OEM Ford Shelby GT500 Mustang 6-piston caliper, a factory-production monobloc built for a 3,850 lb muscle coupe, so it has the piston area to clamp the 400 mm carbon-ceramic disc with consistent, repeatable pedal travel lap after lap.
Rear Caliper
The rear uses your choice of Brembo 4-piston caliper on a 370 mm disc: V4 (OEM Cadillac CTS-V), GT4 (Brembo GT | M4), or GTS4 (Brembo GT | S4). All three add rear thermal capacity and are matched to your car's factory electronic parking brake.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.

FAQ
Will this fit my M240i or M2 if they share the same chassis name?
Not automatically. The G42 M240i and the G87 M2 share a family name but differ mechanically at the front knuckles, hub geometry, and wheel clearance, so we engineer the brackets, rotor-hat offsets, and caliper mounting to your exact confirmed trim. Nothing here is a platform-wide bolt-on assumption.
What wheels do I need to clear this kit?
The front rotor is 400 mm, so 20-inch wheels are the minimum. Anything under 20 inches will not clear the disc, and spoke geometry matters too, so send us your wheel details and we will confirm caliper and spoke clearance before you buy.
How do these behave in cold winter driving?
An untuned cold carbon-ceramic disc bites less than cold iron on the first stops. That is physics, not a defect. We optimized both the pad compound and the disc's ceramic coating for cold starts, so cold-car feel now comes very close to summer feel. On the coldest first stops, leave a little extra following distance until the system is warm.
Does this keep my electronic parking brake working?
Yes. The G42/G87 uses a factory electromechanical parking brake in the rear caliper, and all three rear caliper options here (V4, GT4, GTS4) on the 370 mm disc are matched to retain that EPB function with no dashboard faults.
