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" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need 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
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.
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.
Winter & Cold-Weather Braking
Winter question, straight answer: untuned ceramic discs bite less when cold. StopFlex optimized the pad compound and the rotor's ceramic coating for cold operation, so cold-start braking in winter feels very close to warm-weather braking. Extra following distance on freezing first stops is still smart; severe-winter daily cars should run Street Spec.
Caliper Overview
Front Caliper
The front caliper is the Brembo OEM Ford Shelby GT500 Mustang 6-piston caliper, chosen for its high, consistent clamping force on the 380mm carbon-ceramic front rotor. Six pistons spread pad load evenly, so pedal feel stays firm through repeated hard stops.
Rear Caliper
For the rear you choose among Brembo 4-piston options over a 355mm rotor: V4 (Brembo OEM Cadillac CTS-V), GT4 (Brembo GT | M4), or GTS4 (Brembo GT | S4). All three add real rear thermal capacity to balance the larger front, and each is set up for your F44's parking-brake arrangement.
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 a 380mm front rotor fit inside my F44 wheels?
The front rotor is 380mm, so 19-inch wheels are the minimum; anything under 19 inches will not clear the caliper and disc. Spoke shape and inner barrel clearance also matter, so send us your exact wheel details and we confirm clearance before you buy.
Is this really matched to my exact trim, or is it a generic F44 kit?
It is bespoke per confirmed trim. The M235i xDrive uses different front knuckles, hub geometry, and wheel offset than the 218i, 220i, or 228i, so we build brackets, caliper mounts, and rotor-hat offsets for the specific car you confirm. We do not treat the F44 as one platform-wide bolt-on.
How do these brakes behave in winter and on cold mornings?
A cold, untuned carbon-ceramic disc bites less than cold iron on the first stops. That is normal physics, not a fault. We tuned both the pad compound and the disc's ceramic coating for cold starts, so cold-car feel now comes very close to warm feel. On the coldest first stops, still leave a little extra following distance until the system is up to temperature.
Does this work with the F44's electronic parking brake?
Yes. This car uses a factory electromechanical parking brake, and the rear 4-piston option you select is set up to keep that EPB function working. Confirm your trim and we match the rear so the parking brake operates as it does from the factory.
