2019-2026+ BMW M850i (G14/G15/G16) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2019-2026+ BMW M850i (G14/G15/G16) Carbon Ceramic Brake Kit — OEM-Size Replacement
The G14/G15/G16 M850i uses large OEM-size brakes—395mm front and 370mm rear—and owners shopping this kit are usually trying to reduce iron-rotor heat stress, brake dust, and front-end mass without changing the factory brake package. This StopFlex OEM-replacement kit keeps the original rotor diameters and supplies carbon-ceramic rotors, matched pads, hats, and floating hardware for the M850i brake layout. It is built for M850i fitment only where the car matches the listed 395mm front and 370mm rear rotor references.
- OEM-size replacement for 2019-2026+ BMW M850i G14/G15/G16 applications using 395mm front and 370mm rear rotor references.
- Carbon-ceramic discs reduce brake dust and rotating mass compared with the M850i iron rotor package while retaining the factory rotor sizing.
- Kit includes rotors, pads, hats, and floating hardware so the friction system is matched around the M850i 395mm/370mm setup.

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.
Carbon ceramic rotor diameter sets the smallest wheel that clears the caliper. Confirm your wheel diameter and spoke clearance with StopFlex 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 fit every 2019-2026+ BMW M850i?
It is limited to G14 convertible, G15 coupe, and G16 Gran Coupe M850i models that match the 395mm front and 370mm rear rotor sizes listed for this page. Confirm your current rotor diameters, trim, and brake option before ordering.
Does this kit keep the factory electronic parking brake and Auto Hold functions?
Yes, this is an OEM-size rotor and pad replacement for the M850i rear brake layout, not a rear caliper conversion. The factory rear electronic parking brake hardware remains in use when the car matches the listed application.
Why switch an M850i from iron rotors to carbon ceramic?
The M850i is a heavy, high-speed grand tourer, so repeated braking can load the 395mm front rotors with significant heat. Carbon-ceramic rotors improve heat stability, cut visible dust, and reduce rotating mass compared with comparable iron discs.
What should I confirm before buying?
Verify G14/G15/G16 M850i chassis, 395mm front rotor diameter, 370mm rear rotor diameter, wheel clearance around the factory calipers, and whether any previous brake retrofit changed the original M850i hardware.
