The build: what's actually on this 718
| Item | Specification |
|---|---|
| Vehicle | Porsche 718 Boxster (982) |
| Front setup | Porsche GT3 6-piston fixed caliper with 400mm STOPFLEX carbon ceramic rotor |
| Rear setup | Brembo 4-piston caliper (EPB-compatible) with 390mm STOPFLEX carbon ceramic rotor |
| Pads | STOPFLEX low-dust ceramic compound, front and rear |
| Quoted weight saved | About 22 kg / 48 lb total |
| Wheel requirement | 20-inch wheels recommended for clearance |
| Axle scope | Front and rear carbon ceramic conversion |
Confirm before you order: this is a custom conversion, not a same-shape swap. The 400mm front rotor and 6-piston GT3 caliper make 20-inch wheels the practical minimum, and barrel plus spoke geometry still decide final clearance. Send us your exact wheel spec so we can check it before anything ships.
Why this hardware mix works on the 982
| STOPFLEX feature | Why it matters on the 718 Boxster | What you notice |
|---|---|---|
| GT3 6-piston front caliper + 400mm CCB rotor | The 982 is light and mid-engine, so front-end bite and pedal support shape how confidently you turn in. | A firmer first pedal and braking that's easier to modulate on corner entry. |
| Brembo 4-piston rear caliper, EPB-compatible | The 718's electronic parking brake makes a standard GT3 rear swap awkward; this rear is chosen to coexist with the EPB. | Rear clamping force that balances the bigger fronts without parking-brake faults. |
| Carbon ceramic rotors, about half the weight of steel | Rotors are unsprung and rotating mass, exactly where weight hurts a sports car most. | Sharper steering and a chassis that settles quicker over bumps and surface changes. |
| Long-fiber CCB construction | Carbon ceramic gets dismissed as track-only; long-fiber build is made to handle cold street starts. | A normal first stop even around -20°C, no warm-up ritual on a cold morning. |
| Heat-stable friction surface | Back-road pace puts repeated heat into the brakes; iron starts losing precision before ceramic does. | Consistent bite stop after stop; tested surface friction holds around 0.3μ even at 900°C. |
| STOPFLEX low-dust pads, no-rust rotors | A weekend 718 sits between drives, and dirty wheels or surface rust kill the look. | Wheels that stay clean between washes and rotors that don't rust after rain. |
What gets better
- Firmer, more confident first pedal under hard use.
- More stable repeat braking on a fast back road.
- Roughly 22 kg less unsprung mass for sharper steering feel.
- Very low brake dust, so the wheels stay clean.
- No rust after rain and long street life, around 250,000 to 300,000 km off track.
- Crackle-texture rotor finish that suits the 718 behind open spokes.
What to confirm first
- Your wheels: 20-inch is the practical minimum, and barrel plus spoke shape decide clearance.
- Your goal: this is real braking hardware, not a cosmetic-only refresh.
- Rear EPB: the Brembo rear is here specifically to work with the electronic parking brake.
- Pad pairing: run the matched STOPFLEX compound to keep cold bite and low dust.

718 Boxster CCB questions
Why does this build use a Brembo rear caliper instead of a matching GT3 rear caliper?
The 718 Boxster runs an electronic parking brake, and forcing a standard GT3 rear caliper to work with that system is messy. This build uses a dedicated Brembo 4-piston rear caliper that respects the EPB while still giving the rear axle enough clamping force to balance the larger GT3 front calipers.
Will this Porsche 718 Boxster brake setup clear 19-inch wheels?
Usually no. A 400mm front rotor behind a 6-piston GT3 caliper needs the room a 20-inch wheel provides. A few very specific 19-inch motorsport wheels might work, but plan on 20-inch fitment for this configuration and confirm your exact wheel before ordering.
Is this carbon ceramic setup okay for daily street driving?
Yes. The hardware is far more serious than stock, but it's built to behave on the street. With the matched STOPFLEX pad compound, the first cold stop feels normal, pedal response stays predictable, and brake dust stays very low.
How much weight does this upgrade remove versus the steel brakes?
This featured build is quoted at roughly 22 kg, about 48 lb, of total weight reduction. Most of that comes from swapping heavy iron rotors for carbon ceramic discs, which cuts unsprung mass and sharpens how the chassis responds.
How long do STOPFLEX carbon ceramic rotors last on a street-driven 718?
On the street they last far longer than typical steel rotors. Street-use life can reach roughly 250,000 to 300,000 km when the car stays off track, though your real mileage still depends on driving style, pad choice, and how the car is used.
