2021-2026+ BMW M3 / Competition (G80/G81) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2021-2026+ BMW M3 / Competition (G80/G81) Carbon Ceramic Brake Kit — OEM-Size Replacement
The G80/G81 M3 owner usually shops carbon ceramic brakes after overheating the 380/370 mm iron setup on track, fighting heavy brake dust on open wheels, or pricing a cracked 400/380 mm factory CCB rotor at the dealer. This OEM-size StopFlex kit matches the listed M3 rotor references—380 mm or 400 mm front and 370 mm or 380 mm rear—with carbon-ceramic rotors, pads, hats, and floating hardware for lower rotating mass, stable heat behavior, and factory-style fitment around the original brake architecture.
- Built only for the 2021-2026+ BMW M3 / Competition G80/G81 rotor references listed on this page: 380 mm or 400 mm front and 370 mm or 380 mm rear.
- Carbon-ceramic discs reduce iron-rotor dust and corrosion staining on the G80/G81 M3’s exposed performance wheels while keeping an OEM-size package.
- Floating hats and hardware are included so the carbon-ceramic rings can manage thermal expansion during repeated S58 track braking events.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | BMW M3 / Competition (G80/G81) |
| Model years | 2021-2026+ |
| Front rotor reference | M3: 380mm, 400mm (CCB) |
| Rear rotor reference | M3: 370mm, 380mm (CCB) |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 19" (for the 380 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 380 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 fit my 2021-2026+ BMW M3 or M3 Competition?
It fits only the G80/G81 M3 and M3 Competition configurations that match the rotor sizes listed for this page: 380/370 mm or factory CCB-style 400/380 mm. Confirm your front and rear rotor diameter before ordering.
Do I need different wheels for the 400/380 mm carbon ceramic setup?
The 400 mm front CCB package typically requires 19-inch or larger front wheels with enough barrel and spoke clearance. If your car has an 18-inch front wheel package, confirm clearance before selecting the 400 mm front option.
Will the electronic parking brake and auto-hold still work?
Yes, the rear package is designed around the G80/G81 M3’s factory rear brake layout and electronic parking brake function. The kit replaces rotors, pads, hats, and floating hardware; it is not a rear caliper delete or EPB bypass.
Why choose this instead of another iron rotor set?
Iron 380/370 mm replacements are less expensive but keep the same dust, corrosion, and heat-mass behavior. Carbon ceramic is the better choice when the priority is lower rotating weight, cleaner wheels, and more consistent high-temperature track behavior.
