Read this before you order
This is a mixed front-and-rear configuration, not a single universal part number. The front is a dedicated Brembo GTS big brake package; the rear is a direct-fit rotor that works with the factory BMW M caliper so the electronic parking brake stays exactly as stock. Wheel clearance and exact component selection should be confirmed for your specific car before ordering.
What Changes on the Road
| STOPFLEX setup | Why it matters on the G80 | What you notice |
|---|---|---|
| Brembo GTS 6-piston + 380mm CCB front | The front axle carries most of the braking load and the most heat, so the biggest hardware belongs here. | Sharper, more progressive front bite and better composure during repeated heavy stops on a canyon road or track day. |
| Carbon ceramic rotors, all four corners | A STOPFLEX rotor is about half the weight of a same-size steel disc, and rotors are some of the heaviest unsprung parts. | Less unsprung mass, which sharpens how the car reacts over rough pavement and through quick direction changes. |
| STOPFLEX pads with CCB rotors | Factory-style M pads throw heavy black dust that cakes onto open-spoke wheels fast. | Dramatically less brake dust, so the wheels stay clean and washing gets a lot easier. |
| Factory rear caliper retained | The G80 rear caliper houses the integrated electronic parking brake, so keeping it avoids a complex conversion. | The EPB works exactly as stock while the rear rotor moves to the same carbon ceramic material as the front. |
| Corrosion-free CCB rotors | The M3's open-spoke wheels leave the rotor face on full display in all weather. | The rotors don't rust after rain, so the finish stays sharp behind the wheel. |
What gets better
- Stronger, more consistent front-end braking when you push the car hard.
- Far less brake dust, so the wheels stay clean between washes.
- Around 18 kg less unsprung weight for a more agile feel.
- Rear electronic parking brake keeps working exactly as stock.
- Rotors that don't rust and can reach roughly 250,000–300,000 km of street service.
What to confirm first
- Your wheel clears the 380mm front package — check barrel shape, spoke design and offset.
- Whether you're building mainly for street, canyon or occasional track use.
- That you're pairing STOPFLEX pads with the rotors to get the low-dust benefit.
- Your exact rotor sizing and that you want to keep the factory rear caliper and EPB.

M3 G80 Brake Upgrade FAQ
Why run Brembo GTS calipers up front but keep the factory rear calipers on the M3 G80?
The front axle does most of the braking work and takes the most heat, so that's where the Brembo GTS 6-piston front and 380mm STOPFLEX carbon ceramic rotor go. Keeping the factory BMW M rear caliper leaves the electronic parking brake working exactly as it does from the factory, and a direct-fit STOPFLEX carbon ceramic rear rotor brings the rear axle into the same material and heat family as the front.
Does this upgrade change how the electronic parking brake works?
No. Because the factory rear caliper stays on the car, the electronic parking brake operates exactly as it did from the factory. You upgrade the rear rotor material without touching EPB function or adding a separate rear caliper conversion.
Will the 380mm front setup clear 19-inch wheels on a G80?
This build is intended to work with 19-inch wheel setups, which is part of why it suits owners who want common 19-inch track tire sizes. Wheel barrel shape, spoke design and offset still decide actual clearance, so confirm your specific wheel before you order.
Will this cut the brake dust on my M3 G80?
Yes. When STOPFLEX carbon ceramic rotors run with STOPFLEX pads, brake dust drops sharply compared with typical factory-style M performance pads. That means cleaner wheels and a lot less of the heavy black grime M owners deal with every week.
Is the Brembo GTS plus STOPFLEX hybrid setup good for track days?
It's built for owners who want stronger repeated-stop performance than the stock iron brakes, especially up front where heat builds fastest. The Brembo GTS front caliper and STOPFLEX carbon ceramic rotors improve heat consistency, but track suitability still comes down to your tires, pads, pace and how the car is used.
