2021-2026+ BMW M4 / Competition (G82/G83) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2021-2026+ BMW M4 / Competition (G82/G83) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2021-2026+ BMW M4 and M4 Competition G82/G83 use large OEM brake packages, and this StopFlex kit replaces the listed factory-size rotors without changing the car’s caliper architecture. Choose the 380 mm front / 370 mm rear package for iron-brake cars, or the 400 mm front / 380 mm rear package for M Carbon Ceramic Brake cars, then pair the rotors with the supplied pads, hats, and floating hardware. The carbon-ceramic construction targets repeated high-speed heat control, lower brake dust on open M wheels, and reduced rotating mass compared with equivalent iron rotors.
- Built only for G82/G83 M4 fitments using the listed OEM rotor sizes: 380 mm front / 370 mm rear or 400 mm front / 380 mm rear CCB.
- Includes carbon-ceramic rotors, matched pads, hats, and floating hardware so the rotor assembly matches the selected OEM-size brake package.
- Designed for M4 owners replacing worn iron rotors for lower dust and heat stability, or replacing cracked OEM CCB rotors without buying dealer rotors.

| 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 kit fit every 2021-2026+ BMW M4?
No. This page is limited to G82 coupe and G83 convertible M4 / M4 Competition cars with the exact rotor sizes listed: 380 mm front / 370 mm rear or 400 mm front / 380 mm rear CCB. Confirm your rotor diameter before ordering.
Does the kit keep the factory electronic parking brake and auto-hold functions?
Yes, when ordered for the correct G82/G83 rear brake configuration, the kit replaces the rotor, pad, hat, and floating hardware while retaining the factory rear caliper and electronic parking brake system.
Why switch a G82/G83 M4 from OEM iron rotors to carbon ceramic?
The main reasons are lower brake dust, reduced rotating mass, and better resistance to heat buildup during repeated hard stops. On a heavy turbocharged M4 used for fast road driving or HPDE sessions, those changes reduce the workload on the brake system compared with iron rotors.
What should I confirm before ordering?
Confirm chassis code G82 or G83, trim, current front and rear rotor diameters, whether the car has the factory M Carbon Ceramic Brake package, wheel clearance for the selected brake package, and any non-OEM calipers or spacers.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
