Confirm before you order
This is a rotor-only path built around the factory M Compound brake package and the OEM 19-inch front / 20-inch rear wheels shown here. If your car runs different calipers, different wheels, or aftermarket brake parts, get fitment confirmed first.
What the upgrade actually changes
| STOPFLEX feature | Why it matters on the G87 | What you notice |
|---|---|---|
| Carbon ceramic rotors at about half the weight of same-size steel | The M2 is short, stiff, and quick to react. Heavy iron rotors are unsprung, rotating mass the suspension and steering have to fight at every corner. | Roughly 25 kg gone where it counts most — the front end feels lighter on turn-in and calmer over rough pavement. |
| High thermal tolerance, ~0.3μ surface friction still holding at 900°C | A 450+ hp car puts huge energy into the brakes on a back road or track day. Iron rotors heat-soak and the pedal goes long. | The brakes stay composed deeper into hard use instead of fading once the iron is cooked. |
| Low-dust ceramic pad pairing | Factory M pads coat wheels fast, and it shows badly on the G87's darker wheel finishes. | Wheels stay clean far longer between washes. |
| Carbon ceramic rotors that don't rust | Iron rotors go orange after rain, a wash, or a few days parked. | Clean rotor faces every time you walk up to the car — no surface rust, no rough look. |
| Normal cold bite down to about -20°C on the first stop | A daily-driven M2 has to work the second you back out of the garage on a cold morning. | First-stop braking feels like the factory system, no warm-up needed. |
What gets better
- About 25 kg less unsprung, rotating mass for sharper steering feel and body control
- Stronger heat resistance for repeated hard stops on a grade or at the track
- Very low brake dust with STOPFLEX pads, so the wheels stay clean
- No rust after rain, washing, or sitting a few days
- Street rotor life that can reach roughly 250,000–300,000 km off-track
- Reflective ceramic finish with crackle-texture coating detail
What to confirm first
- Your car runs the factory M Compound brake package
- Front and rear rotor sizing matches the 400 mm / 370 mm setup here
- Your wheels match the OEM 19-inch front / 20-inch rear arrangement
- No aftermarket calipers or non-standard brake hardware are fitted
- You want lighter feel, cleaner wheels, and better heat control — not a bigger caliper conversion
If you're not sure your car matches the spec shown here, send us your details and we'll confirm BMW M2 (G87) fitment before you order through our BMW CCB collection.

BMW M2 G87 CCB FAQ
My G87 already has M Compound brakes. Why bother upgrading the rotors?
The factory calipers are strong. The iron rotors are the weak link — they carry a lot of weight, hold heat, rust, and throw dust. A STOPFLEX carbon ceramic rotor upgrade keeps your M Compound calipers and cuts rotor mass, improves heat resistance, and drops brake dust way down.
Does this fit under the factory 19-inch front and 20-inch rear wheels?
This build uses a 400 mm front and 370 mm rear rotor sized to work with the factory M brake package and the OEM 19-inch front / 20-inch rear wheels shown here. If your car runs a different brake package or wheel design, confirm fitment before ordering.
Does a rotor-only upgrade mess with brake bias?
No. It keeps the factory calipers and stays within the original rotor sizing, so the stock front-to-rear balance is preserved. You get lighter, cooler-running rotors without changing how the car brakes.
How long do STOPFLEX carbon ceramic rotors last on the street?
In normal street use without track sessions, rotor life can reach roughly 250,000 to 300,000 km. Real lifespan depends on driving style, pad choice, and conditions.
Will the brakes still bite when cold?
Yes. STOPFLEX carbon ceramic rotors give normal braking on the first stop even around -20°C, so daily cold-morning starts feel like the factory system.
