2025-2026+ BMW M5 (G90/G99) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2025-2026+ BMW M5 (G90/G99) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2025-2026+ BMW M5 G90 sedan and G99 Touring put hybrid-system mass behind a brake package that sees high thermal load in repeated highway, mountain, and track braking. This StopFlex OEM-size carbon-ceramic replacement kit is built around the M5 rotor references used on this page: 410 mm or 420 mm front, with 398 mm rear. Carbon-ceramic rotors reduce brake dust and rotating unsprung mass versus iron while keeping the factory-style front and rear brake architecture, including hats, pads, and floating hardware matched to the listed rotor size.
- Built only for 2025-2026+ BMW M5 G90/G99 applications using the page-listed 410 mm or 420 mm front rotor reference and 398 mm rear rotor reference.
- OEM-size replacement design keeps the M5 caliper layout and brake balance instead of converting the car to a universal big-brake package.
- Carbon-ceramic friction rings address the G90/G99 M5 use case: repeated high-energy stops from a heavy plug-in-hybrid M car with less dust on open 20/21-inch wheel designs.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | BMW M5 (G90/G99) |
| Model years | 2025-2026+ |
| Front rotor reference | M5: 410mm, 420mm (CCB) |
| Rear rotor reference | M5: 398mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 21" (for the 410 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 410 mm rotor, so the minimum wheel size is 21". Wheels under 21" 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 2025-2026+ BMW M5 G90 or G99?
No. Compatibility is limited to the exact G90 sedan and G99 Touring trims and rotor sizes listed for this page. Confirm whether your car uses the 410 mm or 420 mm front rotor reference and the 398 mm rear rotor reference before ordering.
Does this replace the factory parking brake or auto-hold functions?
This is an OEM-size rotor, pad, hat, and floating-hardware kit, not a rear brake conversion. The rear package is specified around the M5 398 mm rear rotor reference so the factory rear brake and EPB architecture can be retained when the correct application is selected.
Why choose carbon-ceramic instead of another OEM iron rotor set?
On the G90/G99 M5, the main reasons are lower brake dust, lower rotating unsprung mass, and better resistance to heat-related fade during repeated hard stops. Iron rotors remain appropriate for low-cost service; carbon-ceramic makes more sense when wheel cleanliness, heat capacity, and long-term performance consistency matter.
What should I confirm before ordering?
Confirm model code G90 or G99, model year, front rotor reference of 410 mm or 420 mm, rear rotor reference of 398 mm, wheel clearance, and whether your car has factory iron brakes or carbon-ceramic brakes. VIN and clear photos of the current front and rear brake assemblies help prevent a rotor-size mismatch.
