BMW M3 G80 Brake Configuration
| Build item | Installed configuration |
|---|---|
| Vehicle | BMW M3 (G80) |
| Upgrade scope | Front and rear CCB rotor conversion retaining the factory brake calipers |
| Front caliper | Factory BMW M six-piston caliper |
| Front rotor | STOPFLEX 400 mm CCB rotor |
| Rear caliper | Factory BMW M single-piston rear caliper |
| Rear rotor | STOPFLEX 370 mm CCB rotor |
| Brake pads | STOPFLEX high-performance ceramic brake pads |
| Wheel fitted | 21-inch wheel |
| Installation hardware | Fixing bolts and screws |
Fitment check: A 21-inch wheel does not guarantee clearance; confirm the exact wheel model, offset, inner-barrel shape, spoke profile, factory brake configuration, and caliper clearance before ordering.
What Changes When the G80 Moves to CCB Rotors
| STOPFLEX feature | Why it matters on this BMW M3 G80 | What you notice |
|---|---|---|
| 400 mm front and 370 mm rear CCB rotors | The conversion upgrades both axles instead of changing only the heavily loaded front end, while retaining the original BMW M caliper layout. | A complete front-to-rear material conversion without replacing the factory calipers. |
| Long-fiber CCB construction | STOPFLEX CCB rotors weigh about half as much as same-size steel rotors, reducing rotating and unsprung mass at each corner. | The suspension has less wheel-end mass to control, which can sharpen response during braking, turn-in, and quick direction changes. |
| Higher repeated-heat tolerance | Fast road driving and track sessions put repeated thermal loads into the front rotors rather than a single isolated stop. | More consistent brake response as rotor temperature rises through successive heavy braking zones. |
| Factory-caliper compatibility | The upgrade keeps the original six-piston front and single-piston rear calipers instead of replacing the complete hydraulic system. | The familiar factory control layout remains while the rotor and pad friction system changes. |
| Matched STOPFLEX ceramic pads | Rotor material alone does not define braking behavior; the pad controls bite, dust, noise, temperature response, and rotor wear. | Very low visible brake dust and a friction pairing designed for the CCB rotor surface. |
| Corrosion-resistant rotor surface | Iron rotor faces can develop visible orange corrosion after rain, washing, or extended parking. | The exposed rotor surface stays free from the rust film associated with steel discs. |
What gets better
- Lower rotating and unsprung mass at all four corners
- Greater consistency during repeated heavy braking
- Far less visible brake dust with matched STOPFLEX pads
- No orange iron-rust film after rain or washing
- Front and rear CCB conversion without replacing the factory calipers
- A larger 400 mm front rotor presence behind the 21-inch wheels
What to confirm first
- The exact G80 model year and factory brake configuration
- Existing front and rear rotor dimensions and mounting specifications
- Hub, rotor offset, and caliper alignment
- Inner-barrel and spoke clearance on the exact 21-inch wheel
- Correct STOPFLEX pad and installation-hardware pairing
- Professional installation, brake bleeding, and a complete bedding cycle
- Brake-fluid and inspection requirements for the intended street or track use

BMW M3 G80 CCB FAQ
What does this BMW M3 G80 CCB upgrade replace?
It replaces the front and rear iron rotors with 400 mm front and 370 mm rear STOPFLEX CCB rotors while retaining the factory six-piston front and single-piston rear brake calipers.
Will this STOPFLEX CCB setup fit every BMW M3 G80?
Fitment must be checked against the exact model year, factory brake configuration, hub specifications, wheel design, and caliper clearance before ordering.
Does a 21-inch wheel guarantee enough brake clearance?
No. Wheel diameter is only one factor. Inner-barrel shape, spoke profile, offset, and caliper clearance must also be checked on the exact wheel.
Why upgrade the rotors if the factory M calipers are retained?
The upgrade targets the rotating components. STOPFLEX CCB rotors reduce unsprung mass, tolerate repeated heat, resist corrosion, and produce very low dust with matched STOPFLEX pads.
Can this BMW M3 G80 CCB setup be used on track?
The added heat tolerance is useful under repeated heavy braking, but track reliability still depends on correct installation, proper bedding, suitable brake fluid, regular inspection, and pads matched to the workload.
