Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2014-2021 BMW 2 Series / M2 (F22/F23/F87). This page's exact brake setup:

Option 1: Brembo OEM Cadillac CTS-V 4-Piston Caliper — 355 mm rotor Option 2: Brembo GT | M4 4-Piston Caliper — 355 mm rotor Option 3: Brembo GT | S4 4-Piston Caliper — 355 mm rotor |
19" |
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 380 mm rotor sets the minimum wheel size at 19" — 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
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.
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.
Winter & Cold-Weather Braking
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
Caliper Overview
Front Caliper
The front runs the Brembo OEM Ford Shelby GT500 Mustang 6-piston caliper, clamping a 380mm carbon-ceramic rotor. It's a production Brembo unit with consistent pad-to-disc contact across all six pistons, so pedal feel stays firm from the first stop through repeated hard braking.
Rear Caliper
The rear uses a Brembo 4-piston caliper on a 355mm carbon-ceramic rotor, chosen from three options: V4 (Brembo OEM Cadillac CTS-V), GT4 (Brembo GT | M4), or GTS4 (Brembo GT | S4). All three add real rear thermal capacity for balanced heat management under repeated braking.
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 these calipers clear my wheels?
The front rotor is 380mm, which sets a 19-inch minimum wheel diameter. Wheels under 19 inches will not clear the caliper, and spoke shape matters as much as diameter. Send us your exact wheel model and offset and we'll confirm clearance before you buy.
Is this a true bolt-on for any F22/F23/F87?
No, and we won't claim that. The standard 2 Series cars and the M2 use different front knuckles, hub geometry, and wheel ET clearance, so brackets and rotor-hat offsets are cut for your confirmed trim. We build each kit to your specific car, not the platform.
How does this handle repeated track sessions without fading?
That's the point of carbon-ceramic on this car. The 380mm front and 355mm rear discs run our carbon-ceramic-specific low-metallic pad, roughly 0.44 average friction and stable to about 750 C with strong anti-fade behavior. On the M2 that means consistent pedal feel session after session, where a thin iron setup would already be smoking.
How do these brakes behave in cold winter weather?
A cold, untuned carbon-ceramic disc bites less than cold iron. That's physics, not a defect. We optimized both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now comes very close to summer feel. On the coldest first stops of the day, leave a little extra following distance until the system is up to temperature.
