2018-2023 BMW M5 / Competition (F90) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2018-2023 BMW M5 / Competition (F90) Carbon Ceramic Brake Kit — OEM-Size Replacement
The F90 BMW M5 and M5 Competition put heavy thermal load into the factory 6-piston front and single-piston rear brake package, especially on fast road use or repeated track sessions. This StopFlex OEM-size replacement kit is built around the M5’s listed 395 mm iron / 400 mm CCB front reference and 380 mm rear reference, giving owners a carbon-ceramic service path for lower dust, reduced rotating mass, and better fade resistance without changing the intended brake layout.
- Fits only the 2018-2023 BMW M5 / M5 Competition F90 applications covered by this page and the listed OEM-size rotor references: 395 mm front iron, 400 mm front CCB, and 380 mm rear.
- Designed around the F90 M5 brake architecture: large fixed front caliper package with a 380 mm rear disc and retained rear parking-brake function when matched to the correct configuration.
- Carbon-ceramic discs reduce brake dust and rotor mass versus the factory iron setup, a visible benefit on the F90’s open M wheels and a functional benefit for steering response and repeated high-speed braking.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | BMW M5 / Competition (F90) |
| Model years | 2018-2023 |
| Front rotor reference | M5: 395mm, 400mm (CCB) |
| Rear rotor reference | M5: 380mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 395 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 395 mm rotor, so the minimum wheel size is 20". Wheels under 20" 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 my 2018-2023 BMW M5 or M5 Competition F90?
Fitment is limited to the F90 M5 and M5 Competition configurations listed for this page and the matching rotor sizes: 395 mm front iron or 400 mm front CCB reference, with 380 mm rear. Confirm year, trim, VIN, wheel size, and current rotor diameter before ordering.
Does the rear electronic parking brake and auto-hold still work?
Yes, the kit is configured as an OEM-size replacement for the F90 M5 rear brake layout, including the 380 mm rear rotor position. The electronic parking brake and related factory functions depend on using the correct rear configuration for the car.
Why replace the factory iron brakes with carbon ceramic on an F90 M5?
The F90 M5 is a heavy, high-power AWD sedan, so repeated hard stops can overheat iron rotors and pads. Carbon-ceramic rotors are chosen to reduce dust, lower rotating and unsprung mass, and maintain more stable braking behavior under repeated heat cycles.
Can this replace worn or cracked OEM BMW carbon-ceramic rotors?
Yes, when the car already has the compatible 400 mm front and 380 mm rear carbon-ceramic setup listed for this page. The StopFlex kit includes carbon-ceramic rotors, pads, hats, and floating hardware, so the order must be matched to the exact factory brake package.
