2022-2026+ BMW i4 M50 / M60 (G26) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2022-2026+ BMW i4 M50 / M60 (G26) Carbon Ceramic Brake Kit — OEM-Size Replacement
The G26 i4 M50/M60 carries high EV mass and regenerative braking can leave the friction brakes under-used on the street, then heavily loaded during repeated high-speed stops or track sessions. This StopFlex OEM-size carbon-ceramic kit replaces the listed 374 mm or 395 mm front setup and 345 mm rear setup with carbon-ceramic rotors, matched pads, hats, and floating hardware to reduce rotating mass, cut visible iron dust, and improve fade resistance while staying within the factory brake package dimensions.
- Built only for 2022-2026+ BMW i4 M50/M60 G26 applications using the listed 374 mm or 395 mm front rotor and 345 mm rear rotor references.
- OEM-size replacement layout retains the factory caliper architecture and brake bias instead of converting the G26 i4 to a different big-brake package.
- Carbon-ceramic rotors reduce unsprung and rotating mass at all four corners, which matters on the heavy dual-motor i4 M50/M60 chassis with large open-wheel designs.

| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 19" (for the 374 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 374 mm 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.
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.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
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 every 2022-2026+ BMW i4?
No. This page is limited to BMW i4 M50/M60 G26 cars with the rotor sizes listed here: 374 mm or 395 mm front and 345 mm rear. It is not a universal i4, eDrive35, or eDrive40 fitment page.
Do I need to confirm whether my car has 374 mm or 395 mm front rotors?
Yes. The i4 M50/M60 can be associated with different front rotor references, so confirm the front rotor diameter by VIN, brake option, or direct measurement before ordering. The rear reference for this page is 345 mm.
Will the electronic parking brake and auto-hold still work?
The kit is designed as an OEM-size rotor replacement using the factory rear brake configuration, so the vehicle’s EPB and brake-hold functions are retained when installed with the correct rear fitment and service procedure.
Why switch this G26 i4 from iron rotors to carbon ceramic?
Carbon ceramic is mainly chosen for lower brake dust, lower rotating mass, and better heat stability during repeated hard stops. On the i4 M50/M60, those benefits are relevant because the car is heavy, quick, and often run on large wheels that show iron dust quickly.
